What meter are you using? I had this issue with my old JayFlight and a lot of meters are too slow to detect a momentary voltage sag due to the drag from the compressor. I purchased a Hughes Autoformer and it solved the issue. It boosts the voltage coming into the RV so that you have a better chance. That said you also should check your wiring to the AC ensure that it is connected well and nothing has come loose. A bad connection can cause this issue. Another problem is the start capacitor may be going out in your AC.
