Can't be the blower fuse if the blower runs for 5 minutes.
light all the burners on the stove and keep them all on high.
Do they all have high blue flames? If so your propane is fine.
If not troubleshoot your propane system; not your heater.
If the flames are good; the problem is in the heater.
There is a "sail" switch in the outflow plenum that the blower pushes closed that routes power to the gas solenoid to open it to make fire. If that is gooped up with nicotine and/or dust, it won't close.
If your battery is low it won't spin the squirrel cage fan fast enough to close the switch.
If there is dust, grime, or a dead mouse in the fan cage on either side of the motor it will slow the motor enough to not close the sail switch.
control board or gas solenoid could have failed.
Since the thermostat fires the blower at all means the thermostat is OK.
