Engine dies randomly

2004 6.0 cc drw 4wd. Just randomly while driving sometimes the water in fuel light and the wait to start lights come on and the engine shuts off. I can let off the throttle and wait til the lights go off and ease into it and it will go on but if I hold the throttle it will just start bucking. Sometimes when u step back on it, it will shut down again. I have found some posts other places about this same problem but there was no resolution that I could find. It seems like an electrical problem to me. Anybody got a possible solution?

Ok so no replies. Did some more research and found info on harness chafing. I decided to go that route after seeing my exact symptoms. Cranked it up, climbed up where I could reach it and started wiggling the FICM harness and BINGO! Did exactly what it has been doing while driving. Now just getting in there to actually fix it.

Well I think I found it. Shorted wire on #1 injector. Taped it up real good and put a piece of rubber under the spot. It was rubbing on a bolt head. Taped some other slightly chafed spots at the FICM but didn't see any bare wires. Put some rubber under those spots as well. Drove it several miles, starting & stopping a lot. Hasn't done it again. Crossing my fingers! I'll try to post pics.

First pic is intake bolt wire was rubbing on. Second one shows the bare spot near the injector plug.
