JohnyMcFudge, I'm sorry I miss lead you. I meant, and thought you said ICP not CPS. Thats what I meant about unplugging and thought you had oil inside that plug. If it is
chip'd I had mine shut down once for the same reason. It was loose.

Its ok, but I noticed a new light come up. The Water in fuel, Check Engine, and the Check Gage light come up after it stalls. I appreciate all of your help guys.

Ok I got the check gage light to turn off. I checked the oil level and it was low. Now I only have the water in fuel and check engine light. I also drained the diesel in the filter and put in another filter. Now the problem is only occurring during when I hit a pothole or a bump. Any ideas?

Unplug the sensor on the back of the fuel bowl. If its bad it usually blows fuse. Maybe it will help and maybe it won't. Are sure you don't have water in your fuel?

Yeah i'm sure i don't i just drained everything last night. I found the issue if you check my original post again you'll find what I found was causing a short. I don't know exactly here it is, but i will check it out tomorrow. The fuel bowl is fine all the fuses are good and it seems that when i wiggle the wires in the images I attached the truck turns off and comes back on. When I hit a pothole or a speedbump i'm guessing they move and that's what is causing the issue. I will investigate further tomorrow. If you have any idea of what these wires go to and what may be causing it please reply back.

This could be a bit late to get but I can not get the 2 pics of the Red and Black wire mentioned at the end of the first post. If anybody can see them can you tell me where they are in the truck. I am having this same issue and those 2 wires might be my problem.
Thanks

Dangerous situation

Tonight I had this happen with driving rain on the interstate.

Wipers went slow, back wiper went on its own, water in fuel and wait to start lights came on and headlights dimmed and/or turned off.

Came back on its own but did it several times on the way home.

When I got home, i flashed the brights and that stalled the engine.

On and off about 20 times, the rear wiper would go on its own and the left blinker light on the dash would stay on...The headlights would dim when this happens.

Also, none of the buttons on the doors are lit. They used to flicker on and off but now they are off permanently.

Thanks for your help

For that many things to happen all at once, my first guess is battery connections. Ground wires, all battery posts, connections going to the starter, check them all.

I will look at as many connections as possible. I am definitely going to look at the harness. That has caused me consternation in the past.

Any fuse or relays to look at?
I thought it might be the multifunction switch MFS but not so sure now?

It is my wife's and 4 kids daily driver and I need to solve this problem fast.

If I can't find the fix, what are suggestions as to who to get to look at this crazy type of problem?

Thanks
Steve

I had a loose ground on the firewall on the driver side. Aftermarket air filter setup was on the same connection and it wiggled it loose.

Thank you to everyone for your help and suggestions that enabled me to diagnose and fix the problem.
