updating 08 chevy 1500 computer-58

I went to the GMC dealer with my 2003 Chevy 2500HD pickup and ask them to flash the computer and run diagenostics all to find a short in the Throttle body.

I had the throttle body replaced and now the truck runs better than new.

I have replaced the throttle body, had the wires re-connected and shrink-wrapped to the throttle body. I still have problems with the engine shutting down and loss of power. I think the wires are too small and have too many poor quality connectors throughout the wire harness.

I have to pull over and turn the motor off for a while and restart it only to have it happen again. If you know how to fix this problem, Please help me. I have herd that many people have taken their trucks to the dealer only to have this problem return after heavy expenses.

I had the mass air flow changed, knock sensors and harnesses changed, and ignition switch. Took it back to the dealership, they said my battery was bad. Screw the dealership they are as lost as me can anyone help.
