Hey guys, check your Battery cables....If the terminals have any corrosion or battery acid, they replace the terminals and the battery....Thats what happends with mine, the acid was eating through the wires.
Evey time i would play with the high beams, the engine would shudder and sometimes shut off. And the red light would come one.....After i fix every thing, I was fine...check that out first.
