Yes, I agree, and has personally happened to me on occasion. There was an instance though, where the truck did indeed shut right off, the driver swears up and down it turned off, and he did have it towed in. Whether or not the overspeed actually did it, I can't confirm, but I never count anything out with a 6.4
I didn't see any over temps on any of the EGT's that would have shut it off.

Its fixed
Yup,you heard me right, the truck is fixed and starts now, just got to go pick it up Monday.
Turns out a wire was burned and broke apart in the engine harness, so what they did instead of spending hours changing an engine harness was just soldier on a new piece of wire to replace the burnt and broken one. Hope all goes well and we have no more problems, crossing fingers and didn't have any sensor problems.
Thanks for your help guys.
