My duo therm furnace thermostat runs for a fem minutes then stops. I have to restart to get it to run again.

It is provably the high limit switch. Take a look on google for troubleshooting the high limit switch on a furnace.

Where is the fan limit switch on a model 66012-041 duo therm furnace

Here's a good link for you, where you can download a PDF manual for that furnace. The limit switch is normally near back of unit attached to or close to heat chamber. Follow wires that run toward the rear. One will go to one side of limit switch, other will be coming back.
