Hi so my car starts fine when its cold but after it is warmed up to reg. operating temp. it will randomly die as if someone removed the key just on then off no sputtering no backfire nothing, PLEASE HELP, i have replaced the distributor, coil and the ecu. Any insight would be greatly appreciated.

 

check to see if the ecu has blown caps.

 

Sounds like your Fuel Pump ECU is failing

 

when my o2 sensor was bad it would die out after it warmed up.
