SATURN OUTLOOK VENTS PROBLEM

2007 Saturn Outlook

Air Conditioning problem
2007 Saturn Outlook 6 cyl Two Wheel Drive Automatic 44000 miles

My husband just added some refridgerant and the car blew cold and had great pressure. We just drove it to Kentucky and all of a sudden this white vapor came out of vents and the pressure went low and start blowing really low cold air. The pressure seemed to resumed when we would cut the truck off at rest areas and wait for a few minutes and then the pressure would stay on for another 30 minutes, and repeat. Do we need to add more refrigerant or is this a more serious issue?
