A/c weird issue

[Tf79]

2004 Yukon Denali. Already did an evac and recharge, no leaks with the dye we installed. A/c on first start when it’s hot won’t work, compressor kicks on but kicks off. Rev it to 1k, it noticeably kicks on for 15 seconds, cold air, then kicks off, warm air. One truck starts moving it works great ice cold. When I come to a stop it works, not as cold but it’s definitely working. When I get home and put it in park it works. Turn truck off and back on it works. Button turns compressor on and off correctly. It only doesn’t work when it’s hot out and on first start up. I’m so lost lol anyone have this issue before?

Guess, the system is not full or low pressure switch. What are the pressures when this is happening? Ambient temp when happening?

Ambient air temperature sensor(s) or maybe the engine temperature sensor
