this problem has me stumped. While I'm driving down the road the car will just die, everything else is working, lights, radio, heater. You can hear the engine and watch the tach. go down. I've tried pumping the gas pedal while it is dying but nothing will stop it. It won't start up again while it is quietly coasting, but as soon as I stop and put it in park or neutral it will start back up. There was one time where it caught it self and fired back up but that was only once. Please help.
