Well, this has been going on since day 1 when I bought this truck new and it's getting aggrevating. My truck has this gremlin in it that kills the power to the lights and other items when I come to a stop. I'm sure it's going on all the time but it's most noticable during braking. My headlight flash like they were turned off and then on. The engine stalls and then refires. When logging with HPTuners the timing will drop to almost nothing and then back up to normal. While driving the timing will do the drop and recover, too.
Any ideas? I've checked and tightened all grounds and power wires.
