okay, my 1990 chevy lumina starts right up when cold, and will run untill you shut it off. throttle while driving, if you give it more than about 1/3 throttle, it will sputter and try to cut off. once you turn the car off after driving for a while, and wait more than three or four minutes before trying to start it again, it will not start untill it is cool. although during this hot period, if you spray ether in the intake, it will start up for a couple of seconds. the coil packs are getting fire, i changed the plug wires, and fuel filter. please help me.

Check the fuel pressure if its within specs-sounds like its losing pressure due to injectors and fuel pressure regulator leaking to include the fuel pump check valve-
