This isn't an old R12 system, you cannot judge the amount of refrigerant in the system based on pressures. You have a leak somewhere, and don't have enough of a charge left in the system for it to work.
You can get your cold air back by taking it to someone who has the equipment necessary to properly service the a/c.
It may be slow, but at least it's ugly!
It's kicking off because of high pressure, You need to evacuate the system and charge it with the correct WEIGHT of R134A not by pressure alone.
Then see if the problem persists. Also make sure your fans are working correctly, if they don't come on or your fan clutch is toast then you'll get high pressure as well.
A compressor clutch failure will not cause a quick cycle like this. The pressure guage is evidence that it's a high pressure issue.

Is your condenser fan coming on? If not the system will build pressures rapidly and then cycle itself off. One way to tell if it is your condenser fan is to drive about 50 - 60 mph steadily on the highway, especially with the sun down; if your a/c blows cold then but constantly cycles at idle you likely have a bad fan.

Happened with a truck at work. The desiccant bag in the dryer ruptured and clogged the little orifice tupe ( tiny little thing in the line that creates the pressure drop necessary for the system to work). The system would cycle on and off but would not blow cold. Just an idea.
you need a manifold to read BOTH high and low side pressures. without this it's impossible to accurately diagnose an AC system.
