At what temp does the Mamba Monster Thermal cutoff engage?

And what happens when it does. I think i might have experienced it today, after running about 3/4 of a pack at the track the car would kind loose throttle power (steering still worked) for a couple second, then it would start running again. If i took it to my workbench and let it cool down, it ran great for another 3/4ths of a pack, and then it would do the samething... (i checked the voltage of the packs 3.7v each cell, so it wasnt cut off
