Strange AC behavior 2019 S60 T6 Inscription

This has happened 4 times since the car was new (purchased 7/12):

Car sat locked and unused for a day. Only unlocked and re-locked once in 24 hours.
Started out on a 80 degree afternoon Auto climate was already set on 70 degrees from a hot day two days ago.
After traveling about a mile, the AC was a little too cold so I bumped the setting up to 72 on both sides.
After about half a mile the AC quit cooling completely. The fan was still blowing but the air was hot and humid.
I set the temperature all the way down to LO. The fan speed increased but still blew hot air.
No amount of fiddling with temps or shutting AC off/on would produce cool air again.

The only way I found to bring the AC back was to pull off the road, turn off the engine, and restart.
After that, the AC worked normally for the rest of the trip.

The first time this happened, dealer service replaced a pressure sensor 31368366-6.
But the problem remains.

Any Ideas?

Traced to intermittent contact at connector 94-301 pin #39.
So far, the problem seems to be solved.
