93 and later models that have R134A refrigerant as factory fill have a compressor high temp shutdown switch at compressor clutch circuit on comp.
This can make compressor go off for 5-10 minutes if one of two things is happening:
1. refrigerant level is getting low. The unboiled refrigerant on a full system that returns to compressor will cool it. If it's low this doesn't occur and off it goes.
2. If it's over 100 F outside the a/c shutdown will occur due to compressor getting too hot. You can prevent this manually selecting recirc when it's this hot as the recirculated air entering evaporator will allow the return refrigerant back to compressor to coll it down enough to prevent this. Don't let it stay on recirc forever as this will lead to a much increased likelihood of a/c odors. Turn it off recirc at night or when the temp gets back to normal (if it ever does in TX)o
