I NEED HELP WITH MY AIR CONDITIONER, IT WONT KEEP BLOWING COLD AIR.

1999 GMC Sierra • 360,000 miles

I have a 1999 GMC Sierrra 1500, my air conditioner blows cold air for about 5 minutes then its just vent air. If I turn if I turn it off for about 5 minutes and turn it back on, it blows cold again, but for only about 5 minutes. It has been doing this for about 2 years. I have had freone put in, so that is not the issue, Please help. Thank You

So we know for sure the system has the correct amount of charge?Also what are the high and low pressure readings?
