    Go back to the basics. What can shut it down and not show codes? ECM power or ground connections?
    To answer your question no not exactly that. However check all the connectors in the kick panels and behind the door jambs. Green looking connections is a sign.

    Look at the round connector on the end of the qualcomm cable. Chances are it's all green and corroded. If so, clean off corrosion with cleaner and a non-metal brush. Better yet cut it off then either pull it back thru cab or put a plastic bag and zip tie over it. See if that brings your gauges back to life.

    Update:

    Checked out the cable behind the bunk and did not notice anything unusual.

    The truck is not at an electrician which I heard is great at what he does.

    If this truck does not get fixed by these guys, its going to be sold/traded.
