So it runs for a pretty much set period of time then craps out, won't start and will re-start once the engine cools down?
First, no vapor lock. Pressurized fuel systems (EFI) do not generally vapor lock.
Sounds electrical to me and the experience I had with my '96 LT-1 years back was similar to what I decribed above.
DOes it die out quicker, the warmer it is outside?
Mine ended up being a bad ECM. Boat would run great until the engine bay got heat soaked, exaggerated in AZ heat. Then no power to the fuel pump. Turned out the fuel pump driver in the ECM had an irrepairable short that would short out with heat.
