2005 Chevy 1500 truck AC randomly not working

Lately I have noticed that my truck's A/C hasn't been blowing nearly as hard lately. What used to be fine on 2 is now insufficient at even 5. Some of this my be chalked up to the hot Carolina sun, but it seems as though it's not even blowing as hard as it used to. Today while driving to work my A/C would be blowing out cold air, but then suddenly stop. When I say stop, I mean, the fan kept blowing, but the cold air cease to exit the vents.
What's strange is it seems like if I don't drive the truck for a while, the A/C will work again, but after a certain amount of time with the A/C on, it starts up again.
Anyone else have any ideas as to what to try/look for?
Any help is greatly appreciated. If you need any more information, please let me know!__________________

You may be icing up at the evaporator. Get some pressures and observe low side return line for frost of ice,
