It's almost certainly low refrigerant. When the compressor turns on the low pressure side is evacuated, resulting in refrigerant pressure that is low enough to turn off the low pressure switch. As soon as the refrigerant leaks back through from the high side to the low side, the pressure goes up enough to trip the low pressure switch back on, allowing the compressor to run briefly. Just add some refrigerant and you will solve the problem. Most auto parts retail stores will sell you a kit that lets you add a little refrigerant. Add a can to your AC and see how it runs. Use a gauge to add enough for the system to operate at it's optimal level.
