Feigao 9L Question

[Mike_D]

Well i just bought a 9l here and was using it on my twin force with a warrior 9918 also with 12 gp 3300's. I was out driving yesterday and all of a sudden my truck stopped and now when i try and give the 9l some power the motor just kind of stutters. I thought it might be the warrior acting up so i threw it in my buddies e-maxx with 10l and the controller works fine. What the heck happened? I only ran the 9l about 3-4 times and it never overheated or anything like that.
