Check your duct vent outlets, we had 2 of them aimed at the main area thermostat, our front ac would rarely run and would shut off almost immediately when it did come on. I closed the 2 offending duct vents and problem solved, front ac runs like it should. Also, there is 2 circuit breakers outside on your generator, each one controls power to 1 of your ACs, make sure one of them didn't trip.
