The next time it happens, grab a large screwdriver by the blade and rap on the blower motor with the handle. Most of the time it's just a worn out motor and jarring the brushes jump starts it.

You might have a failing blower fan motor. Give the blower motor housing some banging with your hands and if the motor turns on, it is due for replacement.
