Hi, it sounds like need to replace the fuel pump again. It is common for the electric pumps to act up when hot. It you have a fuel pressure gage you can test for a loss of pressure when the problem occurs. you have put 35K on this pump, so it may be getting tired. Two things that can help,extend pump life are never run the fuel,level down to below a 1/4 tank and replace the in line fuel filter every 12k miles. Doing so lessens the load on the pump.

The fuel pump is back in the tank. How would a short stop to cool change things back there. Would conditions in the tank change with time driven.


Even when it is quite warm (we don't see much over 90 in Canada)


it will not be a problem untill we drive a while.


 


THANKS

Expert:  Jerry replied 1 year ago.
The fuel pump is a small electric motor, when it gets hot the speed of the motors slows down causing the fuel pressure to drop. When you shut the engine the pump will cool off rather rapidly, it is submersed in cool fuel. I have had this same problem on many Ford vehicles,mostly the length of time running was more of a factor then the temperature.
