Did anyone have a overheating fuel pump before?

I drive a 2000 Pontiac Grand AM GT.

My car hesitates after 20 kms, if I keep my foot on the gas, the car stalls out.

A mechanic figures it is a overheating fuel pump.

never heard of that b4. but i guess it could be possible. If the fuel pump sock is plugged up the motor would be straining causing it to overheat, but if it was full of gass that should keep it cool. Just a thought

Yep, had that problem with my GA. With less than 1/2 a tank of gas, it would just cut out. It wouldn't restart immediately, but would if I waited a few minutes. Coughed up $700 to have the pump and fuel gauge sender replaced at the dealer, who wouldn't do it under warranty until it failed completely.

Mine would start right away.

on june 28 2004 i ran my tank on fumes, just to see what might have happened.

It never got any worse. It would hesitate at 20 kms or so. it didn't matter how full or empty the tank was.

after I filled the tank, I started getting 60 kms, before it would start acting up.

do you guys think it might be a dirty fuel filter or fuel tank?

The fuel filter is a whole lot cheaper to replace than the pump, so I'd replace that first.
