Car will start and run for about a minute. It's almost like it grounds out and I lose everything. I thought the altenator wasn't charging so it was replaced. Didn't fix it. I checked fuel pressure and there was literally nothing in the fuel rail when I purged it. Car will start if I hold it to the floor but when I let off it cuts off. Sometimes it loses power. Fuel pump is about a month old. Also while im driving in the dark I see my headlights and interior lights diming. Like there is power surging through the car. I think there is something thats causing the fuel pump to shut down. I dont know what though???
