Default 2011 Tahoe- AC Blowing hot air above 95 degrees

Anyone experience an issue with their Tahoe or other Chevy trucks/cars where if the temp reached above 95 degrees or so it blows hot air for 15-20mins? The only way to get it cold is if I’m consistently driving for a good 20mins or so. Once I put it in park in idle it will blow hot air again. Once it’s below 95 degrees outside the AC works well. The Freon is charged. Any ideas?

Do you have the high and low side PSI readings?

Confirm that electric engine fans or fan clutch is operating PROPERLY. And that all shrouding is in place.

When it's blowing hot air, can you put in park and open the hood, and visually confirm if the drive plate of the compressor (the center part) is turning like it should be ?? Last summer I had a similar issue with my 1998 Frontier and I found that I had to remove an AC clutch shim to decrease the gap to fix it.
