Your batery is to small it was intended for the 18th scale you truck is pulling to much from the batery and it can not keep up the voltage and the voltage cut off is shutting it off. Get a higher c rated batery with bigger wires. I had the same problem last year at indy pulling Joes dozer on my lowboy I was trying to use a flight power 2 cell 1800 with 20 c rating it was just to much of a draw on the batery so I put in my common sence 2 cell with a 30 c rating and it worked fine.
