Its what Rich said. I've had the same problems with my Acoms system. If the input voltage drops too low it loses its bind to the TX and starts hunting for it again. Since this can take a few seconds the car kind of stalls for that time.
I had this a lot in my Micro T where the tiny battery can't supply the 10200kV brushless. I swapped to an old 27mhz set and the probelm stopped. The voltage to the rx still drops, but at worst it results in a tiny glitch
