Engine Performance problem
2002 Buick Regal 140000 miles

My 2002 Buick Regal LS stalled on me randomly. I could not get it started but once I got pulled to the top of a hill, it randomly decided to start about two hours later. I only ran it for about a mile before it stalled on me again. But of course, two hours later it started for another mile and stalled again.
When I try to start it right after it stalls, it acts like it is going to start up and almost does for a split second but then dies again. But why when I start it hours later after it cools down will it start for a couple minutes?

My thinking is that it is the fuel pump possibly? Or is it something electric? I just can't get it to stay running and have no idea of what it may possibly be. PLEASE HELP! Thank you!

I am suspecting the fuel pump as well. You need to get a fuel gauge hooked up to it when it doesn't start and make sure the pressure is completely in spec.
(48-55 psi key on engine off)

IF the the pump is bad, replace the filter at the same time.

Post back if it is good.

How do I test the fuel pump with a fuel gauge?

Also where is the fuel filter generally located?

After working on my car yesterday, my car would not start but if I gave it gas it would stay started, but it sounded like it was firing on two or three cylinders. And if I tried to give it more gas, the Rpms would not go up. It just stayed consistant no matter how much gas I gave it. I tried not to keep it running for long cause it sounded so bad, but it was just weird to me. Still thinking fuel pump?

Thanks!

IF it isn't getting enough fuel it can sound that way.

I would still check the pressure. Either you start testing for loss of spark or loss of fuel to begin with. Assuming no codes are present in the pcm.

Fuel filter is along the frame between the rear and front wheels closer to the rear on the driver's side.
