    I've a 2012 Pete garbage truck with Cummins PX8 and allison automatic. Truck runs fine and then just dies. No codes no warning lights no nothing. Turn the key off, then back on and it runs fine. I can't find any visible harness issues.

    The diagnostic computer doesn't read any trouble codes at all. Nothing.

    Thanks!

    Engine harness was my thoughts as well. The whole electrical system shuts down like you turned the disconnect off.


    Thanks!

    18 years as a mechanic for WM. All depends on the body maker for this, but is it a Universal, Labre, Etc? Some builders installed home made tanks at the factory. When it stalls, open your fuel tank cap. If you hear air suck in, the breather is plugged or none existent. After a few hours of sucking fuel, the tank creates a vaccumn and wont let fuel into the engine. Try leaving your cap loose and see.
