AC system shuts down while running on generator. AC Voltage doesn't drop below 125 but system shuts down
 
Your voltage us good, ur you are not getting enough current to the unit so the system shuts down. Get a meter on it and see if you are getting the current into th unit. I am not an electrical guy, but I know you get voltage with on strain still connected, but current gets impeded, kind of like when you have some water getting through an impeller but not enough to cool. Hope this makes sense.
 
Also check or have checked the frequency. If the generator isn't running or putting out 60hz +/-2hz things can go bad quickly.
