truck shuts off randomly and goes (haywire)on/off 3 times per interval.. last instance: did 50mi run and shut down 15-20 times and haywire each time, as explained above. also, a titled code shows as "permanent" but, dealer says truck is "fine" and nothing wrong.. private mechanic stated he could not find out even if he wanted because code also states "contact manufacturer" and dealer will not divulge such information! anyone got any info/help would be greatly appreciated
Code spn521013 shows as permanent, dealer says it's fine.

Check metal bracket above air compressor that has MCM harness zip tied to it. Cut zip ties and open up plastic loom and look for damaged wires. Can high/low wires seem to be the ones that get damaged most often.
