Little back story. Every once in a while when i'm really rodding on my car it would just die out. It would start back up if i just coasted for 3 or 4 seconds (5sp so its just like it was getting bump started) fast forward to this week. It died out of the blue at a stop light. took me 3 or 4 tries to get her back started but it did and i drove it home. the next day i started it and it died a few seconds later. fired it up and putts down the road at about 20 and it died again out of nowhere. started up after a few tries and i turned back around and parked it. i drove it to work today (only 2 miles) and it drove fine. then when i went to lunch i barely made it out of the parking lot before it died. Now it sitting in the bay at work. It'll run for maybe 10-20 seconds and then start sputtering/revving up/dying and then it will die like it runs out of gas. my fuel pressure regulator stays right at 40 (with the vacuum unplugged) and then the car will die and it will go down to 20. Fuel filter was just changed last week. I took it out today to see if the new one was plugged or something but it was just fine. fuel pump primes every time I turn the key. i get 12 volts at both sided of the wire at the inertia switch while its running, while dying, and after it dies the fuel pump relay wasn't clicking or anything while it dies but it click a second or two after it dies.
