This same thing happened to one of my cabin chillers (though not to those extreme numbers) and it ended up being the temp sensor that slide upstream too close to the compressor. Therefore, the system always thinks it’s hotter than it is, keeps running, and goes long/hard enough where it can’t cool the air but doesn’t quite overheat and shutdown. Hope this at least gives you one thing to check.
