Thank you. There is a safety thermostat, or thermal fuse, inside the machine. This will open if it gets too hot, interrupting power to the motor. I suspect this to be the case with your machine. That fuse is mounted on the blower housing, inside the machine, and is pictured below. It can bet tested by measuring continuity through it with a test meter. If found to be open, it will need to be replaced and is available below.
Please let me know if you have additional questions or need clarification. There is no additional charge for any follow up help!
