I def think you are overcurrent. The cont is 90A, but the burst current is only 100 or 110 IIRC. The Esc is designed for hi voltage, and the FETs they use do not have really high burst ratings like lower V escs (compare the specs to the 16018.)

A 8Xl on 4S will def pull above 110A, prolly 120A+ depending on the gearing in bursts for your truggy. Basically is is not the right controller for your setup.

You need to either use a different controller (like the 16018 or Quark or whatever) or get a different motor and batteries. To make the power you want and keep that controller happy, you prolly want to have an 8S setup ( ie a 8S 2500mah pack) and a ~14XL motor. The upside to the latter is it will be a much more efficient setup. You will have very cool temps even with a cheapie motor, and you will have longer runtimes as you are wating less battery power to heat.
