what caused my car to shut down and not restart, and kill the battery on 2003 Cadillac Escalade

while on a battey charger, car will start if starting fluid is sprayed in the air breather, so assuming its the fuel pump, why did the battery die

Your alternator could be bad which of course will kill the battery. You need to get the alternator tested.
