battery power cutting off while going down road

My cable leading to the starter had the insulation burned off by the headers. Sometimes going down the road or on a hill or taking off from a stop the engine would die. I discovered the insulation problem when I wiggled the cable to see if it was loose. The cable shorted against the frame, bunch of sparks. As the engine would move due to torque the cable would short against the frame causing the engine to die.
