i just got a 1/10 drift car a couple week back and i have some problems. when i use it for a minute or so it will just stop. the steering works but the throttle does not. I barely know anything about these cars so i have no idea whats wrong. Can anybody help?

P.S.
I also have stock settings(stock brushes 3300kv motor, stock ESC, and stock 8.4v nimh 3000mah battery)<br type="_moz" />
