2012 t660 circuit failure, truck shut off

If there hasn't been enough problems with this poor kw already, here's a new one...

Now the truck is dying while driving. The dash lights up red stating circuit failure, immediate service required and shuts the truck off! Happened once in the freeway, pulled into a ta, had clogged fuel filters replaced and she ran another 1000 miles, no issues, no faults found. Well just picked up another load and pulling out of the shipper, bam, shuts down, same circuit failure message. After 10 mins she starts up and we head to the ta in denver a mile away. Cannot continue to chance this problem again. Has anyone experience this problem before or have any knowledge of said issues? Again, it's a T660 Studio Sleeper, 2012 with the cummins isx400, eaton fuller 8 speed. These new computer systems drive me nuts and I'm at a loss of where to start looking lol. Thanks for any input guys

 

This truck had been that nightmare truck... egrs, filters, def problems, fuel rails, power steering pump, turbo, ac probs, sensor failure, fuel filters clog in 10k miles or less... should I keep going? Lol. Well it's not my problem I left it at mhc kenworth in denver. Hopefully they can get us rolling soon. Till then it's off to the hotel to drink this bad morning away haha.

 

Well kenworth in denver did their jobs, found the main power wire going into the computer was arching and ready to catch fire! Apparently the wire coming loose is a common problem... oh joy. It's all fixed up now and ready to go.
