I have changed the fuel pump and fuel sensor guage twice, and when I drive the car for awhile, it starts acting like its not getting fuel and starts sputtering and shuts off, if you try to give it gas it sputters enen more. So I have to let it sit awile to start it back up. Could it be my fuel injectors are bad or a gasket or something, please I need a answer please.
Do you

Make sure the intake gasket isn't leaking. Also, check for vacuum leaks.

Hello, just about anything can cause a misfire issue, fuel--spark, whatever. How long since a tune-up, you know, plugs--plug wires--cap--rotor--air filter--fuel filter? Those are maintenance issues, may not fix your problem, but it's a start. Can you check for codes?

If you think it is a fuel issue, use a fuel pressure gage. The last time I looked at a discount auto store the gage didn't cost as much as a fuel pump. Might not be the best, better than nothing.

If your data link connector has 12 cavities like the picture, you use a jumper between terminals A & B, turn the key on, just till the dash lites come on, no crank. The check engine lite goes to flashing, you count the flashes to get get the codes.

I also agree with jacobandnickolas about the vacuum leak.
