The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

If you look at control box at roof unit, they usually use a separate set of wires for furnace. See what colors they are attached to at harness to thermostat. Some just follow other harness, and come out at thermostat. (bypass control box) Once you've determined which 2 they are, join them together & see if furnace starts, as it should. If it does, thermostat is faulty. If not, pull outside cover off & check voltages at furnace. I'm guessing by furnace model that your unit is approx 30 ft , but if it's a park model, you may have 24 volt system on furnace or 12 volt. Another way of confirming is to go to back of furnace where air intake grille is inside your unit, and locate 2 blue wires going to furnace & remove whatever wires are attached to them & connect them together. Furnace should start up.

Here is an interesting possible problem to look in to
First a bit of background on LP gas
Your LP system operates on 1/2 lb of pressure Not much more than a breath of air. Keep this in mind for a minute.
A lot of RV's have been built over the years using rubber hoses to connect LP gas to water heaters, furnaces, and refers.
Over time rubber and LP gas create an oil, if you have a low spot in your rubber line that oil will collect in the low spot - - Remember the 1/2# of pressure from earlier? Does not take a lot of oil build up to over power the 1/2 # of pressure and now you are not getting LP gas to your refer.
This is one possibility. The lines will need to be removed from the refer and other low setting items like the water heater and furnace also from the LP tank regulator and the using NO MORE THAN 10 pounds of air pressure blown out. BE VERY CAREFUL this oil is some really nasty stuff - cover the ends of the lines with a cloth in a plastic bag with some holes poked in the bag and rubber band it on.
But first lets look at some other options
Your refer has to have 12 volt power to it to operate
90+ % of all 12 volt issues are grounding problems.
Make sure you have at least 12 to 13 volts to the refer and that you have a good ground.
Next Are you getting gas flow to the burner?
If you are getting gas try changing your thermocouple They run a couple of buck and is an easy test.
If you have 12 volt power and gas have you noticed an ammoina smell?
This model has been known to lose the cooling unit
Hope this helps
