Based on your description, it sounds like the compressor was shutting down on a low pressure safety switch. When the evaporator gets too cold, for whatever reason, the refrigerant pressure drops. When the compressor "short cycles", it draws very high amperage on startup. This may have been causing your breaker to trip. Check that your filter is clean, and make sure you are running the fan speed on high. A dirty filter will cause a restriction of air at the evaporator, thus making it colder. Low fan speed may not move enough air across the evaporator. Possibly even a refrigerant leak, which would not be good.
It's possible to be short cycling on high head pressure too, but when you say you raised the tstat temp and it ran ok the latter seems more likely.
It could be electrical too, but a bad compressor capacitor usually will not allow a start up, without tripping the breaker.
Also possible there was a temporary drop in voltage at the post, which may cause this condition. Just a few things to think about.....good luck!
