Shurflow fan shuts down

Hello all,

I have a new Safari Sport 17 and for the initial 20 - 25 nights, the Shurflow fan worked flawlessly. On my latest trip however, the fan will turn itself off after it runs for 20 - 30 seconds. If I wait for a minute or two, I can turn the fan back on, but it again shuts off after 20 - 30 seconds. This model is basic outflow only, no auto cover raiser, nor thermostat, etc. There doesn't seem to be anything constraining the free-turning of the fan.

Does anyone have an idea what to check next?

Does it do this on all fan speeds? Low, medium, and high?
It is possible you have a fan motor that is drawing excess current, and either a thermal protection device or circuit breaker is opening to keep it from causing a fire.

The Shurflo has a variable speed control, but yes it seems to shut itself off even if I use the slowest speed . . must be a faulty circuit . . it would shut off during the day (still 95 degrees here in Phoenix) or at mid-night (65 degrees) at about the 20 second mark.
