Interesting, not to speculate and start rumors, but this was the only video of that event that I could find. It COULD be at 11:01, but again this is all my speculation. I don't want to spread false truths or things that are incorrect so again, this is my speculation.
Also having worked a few events in the past, safety can't be stressed enough at any event. I see some promoters who are either not as familiar with how these trucks handle, how bad their sight lines are or are just ignorant to the necessary safety precautions and it could be detrimental to the entire industry god forbid something happens at ANY monster truck event.. After having been around trucks moving in the pits, performing and on the floor after a run, there is no amount of safety that is too much. I used to question FELD and their decisions to be trigger happy with the RII after parts breakage or a flat tire or something else, it's never a bad idea to shut trucks off for safety reasons. These machines are designed to be as safe as possible, but things happen, parts break and can become unsafe.
