Minn Kota Power Drive Not Working?

Trolling motor is approximately 2 years old, and has worked fine up to this point. Basically what is happening is that it won't do anything, almost like there's no power running to either the foot control or the handheld remote. However, when i unplug it and plug it back in, the motor that rotates the shaft wants to rotate 360 degrees or so. theres power running to the motor but i cannot control anything. I've charged the battery (its good), checked all connections and have done everything else i can think of. Any thoughts as to what may be the cause? Is there a reset button that I haven't seen?Minn Kota Power Drive Not Working?
