7.3 randomly quits

I have an 03 f350 7.3 the truck starts and runs great then out of nowhere it will quit like you turned the key off. After pulling over it will start up and away we go might run a 100 miles or it might not run for 5 miles. The thing is when you pull over unless you turn the key to off it will not start.
turn the key off fires right up I have replaced cps icp and irp.
Some time I want to associate the quiting when I hit a bump or pothole
not to sure . Could use a little help just today pulling the camper it quit at 70 mph what a ride cant steer or stop w/10,000 camper. it quit 5 times in 20 miles after we got off the interstate. any info would help the thing is that it starts up.

Try a new cam position sensor. Get it from Ford or International.

Re: 7.3 randomly quits

To properly diaganosis you need a good scanner. Ae is 350$ its a great investment if you plan on owning the truck for any sort of time.

Besides you'll probably waste that trying to fix it by throwing parts at it.

Re: 7.3 randomly quits

As FL said - make sure the bolt on the engine side of the firewall is tight. There should be a black plastic box that the PCM is enclosed in on the inside as well. It supports/protects the PCM - held to the kick panel with a couple of small bolts.
