Too few details on equipment to do more than guess. If its an electric fuel pump feeding a carburetor, I'd install a fuel pressure gauge mostly because of the new fuel pump. I always look at recent work (the new fuel pump) as the most likely cause of a new problem. It would be nice to know the fuel pressure AFTER the symptoms arise. . . . Second, I agree with joyridin' about checking for fuel inside the carburetor after the engine dies. If you discover that the car won't run when there is obvious fuel at the carburetor, it almost has to be the ignition system.
