2003 Prostar bogging down

I've been fighting this for 3 weeks, and I've scoured these forums, but I am totally stumped.
2003 Prostar 205V 5.7 MCX. So far I have cleaned the fuel tank, changed the fuel pump, new fuel filter, new MAP sensor, new throttle position sensor, cleaned the throttle body.
The boat cranks and idles fine, as soon as I give it some throttle, it tries to plane out, then loses all power. I talked to a mechanic, he said to take the gas cap off and run it, so I did, and it runs great. What would cause this? A fuel line collapsing?

2003 230 VRS bogging down

I am have the same problem, start and idles perfect. Runs for 20 -30 minutes no issues then hogs down but never dies. Throttle back to idle and it will run about 10 mph. Doesnít seem like a fuel pump issue. How do you check the vent line issue you speak of? Any help would be greatly appreciated, I have searched the web and donít find much.
