The refrigerant level is probably low. When the compressor turns on it pulls refrigerant from the low side and as soon as the low side pressure drops below a certain point, the sensor disengages the AC clutch. If you haven't already converted your AC to 134A, now would be a good time. All vehicle AC compressors leak a little refrigerant, simply because of the design of the system. The system may not have any serious problems even though it has lost a little pressure.
