There are several things that can cause a motor to overheat. The basic cause is more load than the motor is designed for. Some causes have already been mentioned: Pushing the power/torque limits of the motor and poor air flow.

Another problem can be side loading on the shaft or excess friction in the drive system caused by poor installation or design. This might not show up in practice, but become a problem after things move during the competitions.

Another cause of overheating can be rapid accelleration and deceleration (especially going from full forward to reverse quickly). The speed controllers may have the most problems with this one, but the motors get hot also. Either way, the motor stops for the match.
