Thanks for all the great ideas! I was starting to suspect the crank sensor. I will have to give that a good looking at. I will also do as suggested and unplug the EHA when itis hot. I'll let ya know what happens.

As far as the fuel relay, if it is cracked, will the pump still cycle when the key is turned on? Is there another circuit that controls the pump function while the car is running? Just curious, I will check the relay for cracks in any event.

The car idles fine................right up to when it gets this problem. It starts to hunt, ever so slightly at first, then I can 'feel' the engine start to shake.....just a hint of shake (miss) then it will hunt more extensively, like large RPM changes until it dies. Then absolutely NO restart until something either cools or resets itself.

I'm going out now to tinker a bit.

Thanks Again,
Sam
