Air conditioning systems are built to "protect" themselves. Couple of points:
Just not familiar with your system, but with it being only four years old, I'd assume it uses an oriface tube.
Doubt if the freon is low; it would never get cold in the first place.
I'll just bet that oriface tube screen is about 95% plugged and the hi pressure is going thru the roof tripping the hi pressure switch open and shutting everything off.
Also, tractors are real bad about getting dirt in the evaporator core; they flat plug up with mud.
Need a set of guages on this bird to see what is happening. If the high side gets upwards of 350 lbs, something is plugged.
Secondly, if the system happens to use an expansion valve set up, the dude is freezing up and shutting itself down after a period of time.
Are you running that temp control all the way over on "max cold"? A good clean system ought to perform very well at "mimimun cold". At "max", the evaporator is never allowed to thaw itself and will just continue to build up ice around the core.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
