Well that was a frustraiting couple of hours. I have the boat tank directely on the fuel pump and it still does it. The shield is on the pump and the pump is cool to the touch so I am ruling out vapor lock. The mechanical fuel pump came out of an M37 that I have never had a problem with so I am starting to believe that the cam on the crankshaft that operates the fuel pump may be warn and be the source of the problem. The only thing that bugs me is why does it not happen until the engine has been running for a while?? Robert.
