Mh was parked all winter. Yesterday morning we used both furnaces and they worked fine. This morning the front furnace comes on blowing for a minute then shuts down. What should we check first?

You have LP, is it turned on? Not trying to be crass and overstating the obvious. But that would be the first thing I'd check.

What make, and model is it? If Atwood, they have a regular problem where the electronic circuit board gets mild corrosion on the board connections where the multi-conductor plug is plugged in. I pull the plug, and clean the tabs on the board with a pencil eraser. That usually fixes it.
What others suggested also, particularly mud in the vent pipe.
One other suggestion is the green ground wire may be corroded where the screw is. Loosen it and re-tighten it. That is a common problem after setting also.
Today is my personal best for most consecutive days alive.

Isn't there a thing called a sail switch? - I think that is what I have to mess with if mine does not start. Usually it is from sitting for a long time not getting used. I seldom use my furnace and usually only in the spring. Look on YouTube for suggestions. I have found that the best resource.

do you hear the gas valve click after it runs for a bit or the igniter sparking? Sometimes it is easier to hear that outside at the exhaust but if you're able to take the panel off and watch it's good. If either of those are happening your sail switch is fine. If I only had a dollar for every time a sail switch was changed unnecessarily Haha.
I would start with the basics. propane on and full, battery voltage good enough, thermostat set high enough (put it on max for testing)
