Doubleteam, welcome to the forum. This is a great place to get and share information about our rigs.
I'm no electrician or electrical wizard, but a couple of things come to mind. One is, do you have adequate power at the pedestal? 110-120 volts. Under current might contribute to that.
One other thing is you may need a different starting capacitor on the AC unit. I have heard of your problem before and one cure was a new starting cap.
That's all I got. I would look into a quick start or easy start capacitor. I don't know the technical name.
Peace
Dave
