Distributor cap?  Fuel pressure?   Did it quit completely?   Sudden
engine quitting usually indicates ignition. Sputtering or slowly
bogging can be ignition or fuel supply.  I'd bet on fuel supply
either he pump, the pressure regulator or something blocking the
line. Does it have a misfire as in one injector not getting fuel?
