good deal i am happy you got it

I just had the EXACT same issue with my 2004 escalade limousine. There is a very small ground wire close to the frame close to the crankshaft position sensor that corroded and had a very small wire. This wire appeared to be attached through the connector but if you pulled on it you would see that it was not attached. This is why it would have an intermittent issue because sometimes it would be touching and sometimes it would not. We cut the wire added a new connector and it was fixed. This small ground is used to allow spark to the sensor. Stupid place for such an important part and it is extremely small for being so important.
