OK, I now caught the time sequence...sorry I missed it earlier. I was completely focused on that video.

And now the unit cools except in the hottest part of the day.
Which tells me that the internal overload inside the compressor may have been weakened by your previous episodes of the fan motor locking up and causing the compressor to become very hot.
If the outdoor coils are dirty, you might try getting those cleaned to see if you can coast through the hot afternoons without the compressor cutting out. If they are clean, and the refrigerant charge is right, you may be on the hook for a new compressor or unit.
Building Physics Rule #1: Hot flows to cold.
Building Physics Rule #2: Higher air pressure moves toward lower air pressure
Building Physics Rule #3: Higher moisture concentration moves toward lower moisture concentration.
