Conclusion:
It was the oil level.
I was finally standing right next to it one time it was shutting down and before it did die, that little oil light went on. I added enough oil so that it was overflowing then quickly put the dipstick back in. I looked all over and found out we didnt even have a funnel in the trailer (on list to get now, LOL), so I had to cut off the bottom of a water bottle and dribbled it in. Enjoyed 2 full days of uninterrupted usage of the gennys to run the AC unit.
