I have an 89 E-150 300 automatic when the weather is 85 degrees or hotter, the motor will start to lose power then die and wont restart for 45mins to an hour-i have put on a new fuel pump relay,new engine control module, rebuilt distributor,cap, rotor. Once when it wouldn't start it had fuel pressure on the fuel rail -didn't have a gauge handy-and had spark and still wouldn't run. Anyone had this problem before... Getting tired of throwing parts at it. Thanks
