I don't have an aftershock, but I do have a Muggy and these trucks are huge and heavy. First, your motor is all wrong. 5700kv is way to high for this application and the motor itself is too small for the job. The esc is marginal, in my opinion. The reason it keeps shutting down is because the motor is pulling too many amps trying to move that truck and heating up the controller. A fan won't help your situation, but FYI, you can run a 5v fan from the aux port on your receiver or a 12v fan straight from your battery pack.
For a truck that size running the MM esc and 12 cells, I'd go with an 8XL motor, or a 9XL. I think the 9XL would be better. In any case, I wouldn't expect any great speed. 35mph would be pushing it. Of course, this is all assuming that your truck weighs about as much as mine. Mine goes over 12lbs.
Many have done trucks with the MM esc, but none that I have seen weigh as much as mine does and I have learned that running the MM in such an application is really pushing the esc. The system (esc/motor combo) is meant for 1/10 scale applications and really won't do well in your aftershock.
If I were you and you wanted to do it right, I'd go with either a Compro 16016 or Quark Monster Pro controller and a 9XL motor to start with. I'd also go to 5S lipo to keep the current draw down with the 9XL. If you stick with 4S lipo, I'd go to the 8XL.
If you go with standard monster truck tires, it will also relieve the esc of some stress.
I'm currently running my Muggy on 4S with the MM speed controller with 40 series masher tires; and I'm very unsatisfied with the truck. I'm running 10/46 gearing, but I have a center diff instead of a tranny. I can't run any more gear because my esc overheats.
If all you want to do is crawl around over rocks and do some hill climbing and speed is not important, then the MM on 4S with the 9XL will do you nicely. If you want any kind of speed, go with a better controller, 5S and the 9XL.
Wish I had something more postive to say about your current setup.

I will admit the 5S is pushing the limits of the ESC and I have likely reduced the life of the poor thing by pushing it that hard. It just has to last me until the Mamba Monster Max or Tekin R1MT comes out!:027:
ASYSTEMERROR - You should be okay with upgrading your motor and batteries. If you intend to stay with the Mamba Max I would invest in a BEC or use the Losi's Rx pack and disable the MM's internal bec.
