No Hot Start, until cool down?

You really need to measure voltage at the pump when this is happening. Measure between the Green/orange wire and the Black/red wire and see what the voltage is. It has to be between the two wires (black probe on one, and red probe on the other).
This will quickly tell if the fuel pump relay and the REM are good or if the problem is with one of them.

O.k. Joe...I will do that, and post the results . Thank You !

Finally got to get some numbers together at the pump. I'm getting between 7.8 volts for the priming shot, and goes up to 8.3 while cranking at those wires you told me to check.

That should be enough for the pump to work. Maybe it's failing.

I did recently install a new pump, to try and eliminate that as a possibility...but I suppose that doesn't guarantee anything. It might be not doing what it should.
