It's a known problem. I bought my vx550 last year in July and it stopped working this year in May. On for 5 minutes, shut down, can't run for a few hours, runs for another five minutes, etc. I called the Nutone customer service department and they exchanged the unit for a new one, cross shipped, via UPS. Mine was still under warranty though. It has to do with some defective thermostat or controller in the electronics of the vacuum.
