Probably start with the basics,fuel pressure,check filter condition.then cps wiring for issues from plug up to main harness. Also look at icp,unplugg connector on pass head and look for oil weeping up into the connector,that is certain replacement needed.

 

The Ford mechanic i had working on mine replaced a few fuses and replaced some of the relays in the fuse box (He did not specify which fuses and relays) and it is now running again. He let it run for several hours and it kept going. We brought it back home and let it run for several more hours and no problems. I then drove it on a 130 mile trip and its acting fine. Crossing fingers for it to be solved! I am carrying a wide array of fuses with me now just in case.
