Have you tried a coil? Sometimes they act a fool when they warm up.

Also for what it's worth I'll add that when I pull the choke on it when its bogging to try and get it going it will pretty much kill it instantly.
Had my ear next to top fuel tank vent under good and can hear it hissing after the ski had been transported like its balancing the task pressure.

So I'm going to bump this again, seems like all along there may have been 3 things occuring all along, all potentially independent of each other.
1. The bad ground on the coil causing random no spark (fixed)
2. Rectifier preventing it from revving (fixed)
3. Bogs out when it warms up, popping and sputtering won't go above idle - ongoing...
Seems like issues 1&2 were present all along but would get masked as soon as the ski would get up to temp and #3 would take over. So now just need to solve #3 and it should be good to go!
Possible things ive found to look into the warm up bog problems:
1. Coil going bad. - was run with a bad ground for a while, seems to work perfect when cold.
2. Fuel tank vents plugged/screwed up.
3. Exhaust hose collapsing internally. - its very easy to squish with your hands hot or cold.

So an update:
First of all thanks Matt Braley for hooking me up with the replacement coil! Im hoping it comes in tomorrow or thursday so I can get a shot at putting this thing on and trying it out before I have to leave for the 4th
Second, I read that using incorrect plugs can kill coils, that being said when I got the ski it had some denso iridium plugs in it, not the correct ngk's. Its displaying all the classic signs of a faulty coil (even though they dont go bad often I know) as seen in some non marine applications ive delt with, slight top end (rpm) miss turns into a severe Popping-backfiring as the coil gets warmer after the first 5-10 minutes out.
I hope to report good results and make this a conclusive resource for future doo-ers soon as the coil arrives!

Getting the right resister plugs in it will certainly help. That may have been the issue all along. The coil will hit your house by Thursday.

You mentioned you cleaned the selector, but I did the same and it ended up sucking air later on. Also it killed the motor when I pulled the choke which was confusing. It would die back down to almost idle and then run fine when I let off. If you pull the knob off the selector you might find residue from leaking gas.

Did it seem time impacted? Im planning on just bypassing the selector for my next test. Just have zero time before leaving so ive got to work fast!
Also I'm sure the PO also ran this thing for a while with the coil ground all loosey goosey which probably doesnt help matters I suspect.

Sooo...
Matt Braley i think can be credited for saving my 4th of july (and much marital tension as well!) but his coil that he more or less donated to my cause was in my mailbox today so i quickly removed the old coil (which had a ton on hidden corosion down in the terminals), clipped a 1/4in of wire off the plug wires, and got the new coil installed and dropped it in the water.
BLAM! its alive and runs for longer than 5 minutes! woo hoo! was out driving for around 45 minutes with the new coil in the rain haha. so now it seems like all the electronicals are in order with this thing at the moment. still has a little hesitation at WOT but im thinking its now fuel related. haven't been actually able to get it running well enough to get a sense of it until now.
so my next step is to pack it up and take it to the aunt and uncles lake house for the 4th now that i know it will actually run for more than a few minutes and really go back through all the fuel and carbs to try and find the little bugger up top.
one other thing ive noticed is that after getting thrown off of it and shaking it all over trying to get back on it has a very difficult time starting back up. any comment on the matter?
in addition to Matt i would also like to thank Nick at OSD marine for taking time to meet up with me one evening as well as Jeff (cant remember his name on here) out by grand lake st mary's for practically helping me a whole Saturday swapping out components and stuff both stand up guys!

WooHoo! Glad to hear it.
It sounds like leaky needle and seats on the hot starts if holding the throttle open helps it start.

Ok, so yesterday took it out for the 4th, made it like 5 laps around the lake, maybe like an hour and a half of running and its back to misfiring through the whole rev range. Prevents you from getting up faster than like 10 mph or so.
Ran it all day with the hose to the carbs plugged right into the reserve pickup in the fuel baffle. Also when it was starting to act up ran it, killed it, and pulled plugs to check fueling they were black with hints of mocha brown on them so fuel seems correct.
Could it be a bad trigger coil that heats up and goes bad? Or the bracket moving as it gets warm?

That sounds like a rectifier/regulator. I know you might have changed it but that's just what they do when they fail so I would change it again.
When going from the RES fitting to the carbs you need an inline filter or the little internal filters in the carbs are gonna catch it all and clog up.

Yea the one that is in there is a new cheap ebay one, but is it possible that the stator is burning them up for some reason? I made some ring terminal leads to connect to the batt, and I think I'm going to run it with my meter hooked up and see if I'm getting any ac voltage when it acts up.
Before doing the fuel lines, the tank was pulled and spotlessly cleaned out. Only has been filed once. I'm putting the water separator back on though since it seems to be un related anyway.

Havent got a chance to install the new boots and the new extra grounding harness that i made. but in the mean time i finally got my video to upload.
in the video its cold, just off the trailer leaving the ramp, start to get it going at 1:30 when i got out of the no wake zone. then i fall off at the end...
https://www.youtube.com/watch?v=F9aoyEO60jg&feature=youtu.be
it seems to run ok (about 45) with a slight miss when cold then as it warms up it will start really screwing up and will pop and miss so bad that it wont get up on plane. dont have a video of it getting really bad yet but hope to soon.

Whole bunch off pictures of the rv pieces parts, was in time btw, maybe +/- 5 degrees of play either way.
Only thing that stands out to me, is there is some oily buildup on the outside of the seam, maybe leaking air when it warms up. Didn't want to run away every though. Can slam the rev limiter on the trailer if you want to...
Plugs pictured started new this is how they looked after a 10 minute ride. Starts out with just a little hesitation on the top end and results in popping and misfiring (can feel it go bang between your legs) bypass fuel bowl, selector, gas cap cracked when starts to act up. On my second new rectifier now.

Your stuff looks fine. This is why every guy needs at least two....so you can parts swap ha-ha.

Well there has to be something wrong, I guess one thing I may have overlooked is my pulse line is black but has an oem clamp on the block side. Its a little loose (can spin freely) I probably should get a new clamp on that...
Edit:
My wife would give me a Viking burial on this thing if I buy another one right now! Just push me out to sea and land a flaming arrow on the gas tank!
