If you are talking about all accessories shutting off with the key in START, this is done by design. It allows maximum power to the starter & ignition for starting the engine.

I am assuming (and we all know what happens then) that the truck will not crank when the key is turned but will when you jump the solenoid with the button. Could be your switch, a grounding issue, a short...
