UL-19 cutting off problem

[Toddly]

Yeah I recently replaced my motor in my UL 19 with a total power TP 4030 CM series I believe it's a 3900 KV and it still running the factory Dynamite 120 amp ESC but now it cuts off after running for a couple minutes it comes on and goes off then goes on and then goes off the guy from Total power asked me if I set the current cut off and what number I set it at that I know nothing about that the specs on the motor are 140 amp is that why it's cutting off
