I have a maristar 225vrs with the Lt1. Usually when we pull some tubes around the boat loses power after awhile. I can't seem to find any rhyme or reason to it other than it doesn't happen right away. It will gradually slow down as you're driving, but if you let off, it won't go any faster than its already going. I can put it in neutral and it will rev just fine, but won't take off again. I did figure out I can turn the boat off, then restart it and it will run just fine for a couple minutes again then the problem returns. I have tried replacing the fuel filter and cleaning the injectors. I've run sea foam and injector cleaner through it. I have not tried a fuel pressure test, but since figuring out the problem goes away after restarting I'm thinking that it isn't a fuel issue. Any help would be greatly appreciated.

Have you checked the fuel pressure?

No, I haven't checked fuel pressure yet. I'm still planning on doing so, but haven't had It back out yet.
