Pulling my hair out

Since it didn't hesitate in the burnout box, I'm guessing it isn't fuel...although it is bucking like my old truck did once when the fuel filter was clogged solid, so it might be worth a quick look. After watching it over and over I would agree that it appears to be some type of g-force related electrical issue. Best way to sort it out would be remove all the fancy bracket racing electronics and start minimal and add 1 piece back in at a time (this would mean completely unhooking power to the T-brake, shift box, etc). Best of luck.

Starting with the ignition box from YR is a good place to begin.
