Help Issue With Mamba Max Esc

[mambarustler]

Hey guys,
Well I bought a Slash 4X4 PE last week after I sold my slash 2wd and my crt.5 roller. So I install my mamba max, medusa 36-50 3300KV motor, 3pm 2.4ghz system, and I noticed a problem. The truck drives perfectly but after a while of turning I start to loose power to steering only, also the fan on the motor and esc stop. Whats causing this? If needed I can make a video for better clarification.

Thanks In Advanced.
