Sounds like your gearing is way too high....try using a 14 tooth pinion and maybe a 46 or 48 tooth spur....are the batteries and/or the ESC getting hot too?

My overall guess would be that the magnets have become debonded from the rotor. It would be worth taking the motor apart (a few screws at the front) to check the rotor. I doubt that it would be getting that hot with some high gearing.
