My truck will start up fine. But will stall out if it sits for about 15 seconds or if I push the gas it will stall automatically. It was fine yesteday. The gas was a little low, so I thought it was that but I put gas in it and it is still doing the same thing. I started it this morning let it warm up 15 minutes it was fine when I first started driving, then it just cut out. Know I can't get it to go any where. Need to know what it may be?

Thank you,
Angie

Check the computerfor any trouble codes, then check the fuel pressure. It should be around 55-60psi.
