Intermittent Cruise Control

hi folks... I've got a '08 F250 XLT that the cruise control has become intermittent. It works most of the time but at times it will "go out to lunch" and not do anything. I've taken the controls from the wheel and didn't see any gummed up coke spills or anything there. It may not be anything but twice when it failed while on a trip I pulled over and shut the truck down. Started it up and the cruise would go back to working. Once I did this and it went back to working only to shut off in about 2 seconds but I was able to engage it again and it kept working. When it stops working there is no green indicator on the dash either. Also I searched but didn't see anything pertaining to my truck sorry if I missed anything.

I hang out in 6.4L Diesel section a lot and I've been seeing threads related to this very problem. The usual culprit seems to be the brake pressure sensor. Located on the (bottom? of) master brake cylinder. The front one of two sensors.

that sensor is exactly where I would start. Replace that and see what you get.

Short of that do you have a scanner? That might pick up the code for it.

nope, no scanner but the swtch sounds like a good bet and not very much money if I can just get in there to replace it. lol

It takes all of maybe 5 minutes to do the job.
