If it quits, I put a different fuel sensor in, and it goes again, until that one gets hot, but that is a pain and I can't rely on that to keep working, with it obviously having a bigger, as yet undefinable issue....Please Help, if you have any advice at all! Thanks

Is it the fuel pump relay getting hot?
How hot warm to touch or smoking?
Was it a new delphi/ac delco pump module or just a el cheapo pump and sender or just a used tank with pump?
Have you checked it to pump and how many amps is pump pulling?
