this could be voltage regulator getting hot or some relay that shuts down when hot if it was your fuel pump you replaced soon as car shuts down remove  last connection from carburetor and see if you have fuel. or if it is fuel injected, check pressure on the fuel rail you will find a valve similar to a tire valve should be a lot of pressure there you can put a pressure gage there and with a manual can check the specs, if you don't have a manual I recommend getting one if you can read you will find it to be worth its weight in gold
