99 F-350, 7.3 with approx. 162,000. It will sporadically shutoff for a second and fire backup while driving on the highway, If it does it when driving in town it will shutoff until I start it.
Any ideas on the possible problem??

 

Sounds like a CPS, does the tach drop like you turned the key off?

Not sure, but will look the next time it happens, probably tomorrow on the way to work.

 

The CPS is pretty common for us most carry a spare. Check to make sure it is not just a damaged connector or cut/chaffed wire before replacing it. It would be wise to carry a spare though. they can be had off ebay for around 50 bucks just search "CPS" unless you would just like to pay Ford 200

 

I just called the Ford dealer for my truck from and earlier post. Since mine is doing the same thing. The dealer said $258.00 bucks and they have them in stock. This would make the 3rd time in two years that mine has been replaced. Since I only have about 40% use of my left arm, and a plate in my neck it is hard for me to replace. But with the plate, I get great cell phone reception.
