It sounds like it might be freezing if the airflow stops.
However if you have very low voltage, say 103 volts, you can have the compressor overheat with high amperage, and trip off for a little while.
At below 105 volts, I will shut off my air conditioner.
In reality, when I get below about 110 volts, I will plug in my voltage booster, and bring the voltage up by 12 volts. Anything between 105 and 132 volts is acceptable for the 110 volt compressor motor.
The local trend is to raise the voltage to lower the amperage requirements. This allows the antiquated power system carry more wattage, while still having less amperage.
I have a voltage meter that displays the voltage in 1" tall digits in my kitchen of the RV. SO I can quickly glance at it, and see if I should be concerned today or not. If it gets close to 110 volts, I will check it more frequently, and plug in my booster.
You can buy a 'Kill-A-Watt' meter that is designed to stay plugged in all the time, and can display voltage. It is about $35 on e-bay. Check amazon.com too.
Good luck!
