Please help - Long. Car troubles.

Yesterday, I was drive home, car was running fine when all of a sudden my car starts to sputter really bad and eventually stall. I tried to restart the engine with no luck. It seemed like the engine wasn't getting enough fuel to start and stay running.

I let the car sit for 30 minutes and tried to restart the engine but this time the car would run for 2-4 seconds then stall. Next, I tried to prime the fuel system by turning the key on and off several time before starting the engine and it worked. The engine ran for about 30-45 seconds before it stalled only this time I watched my fuel pressure gauge while the engine was running and the pressure slowly dropped from 33lbs to 5lbs before it stalled.

I let the car sit for another ten minutes and reprimed to fuel system again before starting. This time I was able to drive the car for 15-20 minutes before it stalled again. I barely made it home that time.

Can someone explain this to me? Any recommendations on what to check? I'm beginning to think that it's my fuel pump going bad.
