ac question again

I have had this issue every year. I only have it shut down after towing 3k lbs on a hot 98º afternoon and stopped in traffic for minutes. Replacement #2 clutch fan didnt help and exacuation and replenish fridgerant niether. I pop the hood and see it not calling for ac and the motor temp slightly above 230º. Could it possibly be that it will shut the ac down when temps go thet high for protection? I cant seem to get this to happen any other times and Ive had thie box on wheels since 01

At this temp the high side pressures can also shut down the system
