I have an 89 GTA (L98), Occasionally while driving my car starts sputtering and it eventually dies, I try starting again right away but it dies once again. But if I let it sit for about 10 minutes, it starts like normal once again and runs fine for about 2 weeks when it happens once again. Is my fuel pump on its way out? Or should I be looking for something else?

 

A fuel pressure test gauge may be your best answer to that quandry.
