Hi Guys & Thank You For Your Help

Problem..

Well My Problem Is My Ski Runs For About 10-15 Minutes.. But Then It Starts To Miss Fire & Bogging Down To Where It Eventually Dies Out. It Starts Back Up Just Fine, But If You Give Any Throttle It Dies. Now I've Let The Ski Cool Down An Tried Again But Still The Same From The Start...


Things I Have Replaced/Cleaned;

Replaced The Spark Plugs
Cleaned Out Injectors
Cleaned Out Air Box

I Need Help..
I've Run Out Of Ideas
 
Sounds like you have the same problem as me. I posted on a thread just hours ago "xpdi bogging down sometimes". Check it out.
Suspect fuel pump BUT you need to check your fuel pressure when running on the water. Also test your air compressor output and fuel regulator as per the manual. Also how long since the fuel filters were changed?

I ordered myself a fuel pump of ebay from high flow. My fuel pressure when running was 100- psi and when it bogged down the pressure got down to 80 psi. It needs to be 107 psi +1 -1.

First check is to check the pressures!

Goodluck
Justin
 
Yep... what he said.

A lot of Di engine issues can be tracked down to low fuel pressure, or low air pressure.
