Fuel pump stops working when engine warm

After we run our 94 ford explorer on a hot day, it will not restart till the engine cools right down. Something is telling the computer not to restart the pump. I have released all the presure in the fuel injector line, and the pump relay will not engage to turn the pump on. I disconected the fuel line before the regulator, and still no pump.
Anybody ever have this problem?

Have you tried replacing the fuel pump relay?

The EEC relay feed the fuel pump relay, perhaps it's having trouble. As tedious as it may be, the solution may be to get a wiring diagram and a multimeter and trace wires until you find the fault in the wiring.
