That high amp switch is a likely place to start. You have a lead from the battery to the switch and two leads from the switch to the motor. All 30 or so amps for the motor goes through that lousy switch. Contacts burn easily and create a dead circuit. There are simple ways to permanently fix the situation if that is your problem. Adding a heavy duty reversing relay and a basic toggle switch make the system nearly bullet proof.
