I was cruising down I-25 the other day and my car started feeling like it was running out of gas. I pulled over and the engine sputtered and died. It would fire up, but would not keep running. I thought I might be out of gas so I got some and when i put the new gas in the car started right up. It had been about fifteen minutes since I pulled over. When I filled up the rest of the way it only took half a tank. My fuel level is estimated on the mileage of my trip set. I had been going about 80 at the time and have not had any problems since. Anyone have any idea what this could be? My guess would be a fuel pump maybe, but which one is it? I know these things have two of them. It's also a non-turbo.
Any help would be great.
