Hello, my name is***** will assist you.

I have never heard of a fuel pump overheating, since it is sitting inside fuel. When the engine stalls, is the VST cover over the fuel pump really hot?

NOT SURE WE BROKE DOWN IN ROUGH SEAS, I WAS TOLD THAT ELECTRIC FUEL PUMPS WILL OVERHEAT IF THE PUMPS FILTER IS GUMMED AND WILL NOT START BACK UP UNTILL COOLED DOWN, I CLEANED FILTER AND VST TANK.

Was the filter on the pump clogged up? If not, the pump is not the cause. We will need to do some further testing.
