New 787 RFI rebuild Running Issue

For the folks who are knowledgable about these 787 RFI's, I have the 2002 model, would you be able to give me advice on troubleshooting steps?
My RFI has a rebuilt engine from reputable shop with fully rebuilt top and bottom end motor
Immediate startup out of water running on hose and in water too
new spark plugs
New Bosch OEM fuel pump and all filters inside fuel pump
cleaned tank added fresh non ethanol gas
New oil lines, filter and oil tank all replaced
Using seadoo BRP synthetic oil, set oil pump advanced for break in

What its doing

While in wake zone for 10 minutes to get to lake no issues running was able to throttle up a little with no issues
Once I gave it throttle to go fast out of wake zone it bogged down then started behaving
like it was running on one cylinder very slow and sputtering barely made it back
to the dock.
No maintenance light
Once I took it out of water I started it up with no issues
running fine again.
Any ideas where I can start troubleshooting with this? Any help would be appreciated.
