I have an 02 7.3 that was running fine. My husband put diesel in it yesterday and drove about 10 miles to pick up a car. Right before he got there, the truck began running rough. He loaded the car and truck still running rough, tried to tow it. He made it about 3 miles and it shut off. He could get it to crank back up but ran rough and would shut off again and again. We put diesel clean in the tank, changed fuel filter, checked batteries, and all lines that we know of. Truck would crank up and idle, but then shut off... after doing this for an hour, we got it running and stayed running for a good 10 minute period. He tried to drive it home. Evry so often, it would do the same, cranknup run for a bit and die out. We finally got the truck home, check over it again. Cranked up and ran completely fine for a good 30 minutes...

Got up this morning, I got the truck to crank up and warm up, 30 minutes later my husband calls and said it shut off on him again about 3 miles from the house... Help!!!
