If the engine light comes on and stays on a scanner should be used to go directly to the problem. If no engine light then normally you look at the fuel pump and new pumps can be bad right from the box, did you have a new fuel filter installed. Other thing to try is when it shuts down remove the fuel filler cap cause if the vent is bad in the cap it will create a vacuum in the tank and that will shut your car down. When you remove it after your car shuts down listen for it to suck a lot of air into the tank. Try starting the car and if this helps leave the cap loose but replace it immediately with a new one.

Just don't be driving it with the gas cap loose.
