    spent oodles and oodles of greenbacks on numerous check engine/stop engine codes with my 2010EPA 2012 Pete 386 I was told all the above and then some except for the guys at Peterbilt in New Haven CT
    and what seemed to to the trick twice now is what they call a "mx power connector" that has wires inside that go bad.

    Yep mine is in the shop right now getting the main harness and abs harness replaced. it started going into neutral while I was driving down the road all by itself. I already had to replace the hood harness for the headlights because they don't put any weatherproofing gel aka dielectric grease in the plug connection. It fried the main plug between the frame and Hood just behind my bumper.
