'97 7.3l shuts off for no apparent reason

Hi Guys, I'm new to forum, but have had my '97 F-350 w/7.3l since new. It has many bolt on mods. but has never left me stranded anywhere for 195k miles.

Now every once in a while it shut off when I come to a stop, but will fire up right away. Sometimes it will do it several times and then won't do it a long time.

The truck has always been well maintained (serviced regularly).

Can anyone make a suggestion way it's doing this. By the way it's not throwing any codes.

Thanks in advance, Steve.

Sorry, posted in wrong forum. Mod please delete. I will repost in correct forum.

The ICP sensor is going bad or the CPS is going bad. My old truck did the same exact thing. If you try to restart it without shutting off the ignition wil lit restart or do you have to turn the ignition off first?

Forgive my ignorance, but CPS is the crankshaft position sensor, correct. I feel like a dummy because I have never had to work on it. It's been that good of a truck.

CPS= Cam position sensor. I just changed mine, got it from international for $45.
its one bolt to change it, in the 10 o'clock position when looking at the crank pulley from the front. lube the seal on the new one before installation.

Failing cam sensors are known for this. Remember the OBS trucks use a different sensor than the super duties
