You've either greatly overheated the motor or been unlucky if the rotor has de-bonded from the shaft.
Most people on oople are racers and run sensored systems, which are more expensive for a race-ready motor and ESC. The EZrun is one of the better inexpensive sensorless systems, so you can either buy another one of their motors and hope for a better life out of it, or upgrade to sensored.
