The air conditioner compressor is not getting power, I used a power probe to apply power to compressor and the compressor kicks on and blows cold air, I then went to the relay and was able to jump terminal 87 to 30 with power probe and once again the compressor kicks on and blows ice cold, not sure where to go next.

System pressures may be low enough to activate the low pressure switch which will shut down the compressor, get the refrigerant high and low pressures checked first post the readings here for further assistance.
