This happens rather frequently, the AC just turns into a fan partway through a hot day. Later on as the day cools down, it starts blowing cold again.
The bedroom AC is about the same, but it takes longer until the AC part of it stops working and it's just a fan.
Both the living room and bedroom AC's will drop water at some point, but it takes longer for the bedroom AC to do so.
We never run the AC in the garage/office long enough for it to tucker out.

Quite a few people will run their A/C fan on low to reduce noise in the trailer. Doing that slows down the velocity of air over the evaporator coils and the condensation that collects on them can't be effectively blown from between the fins on the coils. That sets up the A/C to freeze up (as Javi stated). Check your coils to see if they are icing. If they are and you're running the units on the low fan speed, that may be your problem.
