I'm not sure of your model of A/C, but chances are you might have a bad start capacitor and/or a bad dual run capacitor for the condenser fan & compressor. If the compressor has over heated, it would have gone off on over load. That's a small round piece under the compressor electrical cap. After cooling off, the compressor should come back on. If its a bad capacitor, they are cheap but the labor might be expensive to install. If you are handy(with the power off), you can take off the cover and get a capacitor checker to see the values written on the side of the capacitors. That same meter should also read continuity on your over load if good. A good meter will pay for itself in self repairs. I work in refrigeration and this is a common problem I deal with repairing short cycling compressors a lot from refrigerators, freezers, a/c's, etc. Probably the compressor is not locked up, just an electrical problem.
