I just bought a boat with a hp 500 EFI and the guy I bought it from had drained the tanks he said to get all the old gas out of it. I primed the filter and then used an outboard type hand fuel pump to draw the fuel up to the pump and it ran great after that. Then yesterday I filled both fuel tanks and it lost it's prime again after running for about a minute on the trailer. Any ideas what may be going on?

How is your fuel pressure?
The pump might be going south, after it runs for a while the pump maybe heating up.
Just a guess, though.
You may have to change the fuel filters. Might of been some junk in the tank.

Good idea I will check the filters and pressure. I also thought it may be the pump going out just not sure how to check it.
