You are probably low on Freon. Your symptoms are the way the A/C goes out after running out. A bigger problem is losing the lubricating oil in the A/C system as the compressor can seize if the safety pressure switches fail.
There are several fixes and approaches to each problem. You need to determine if Freon still exists in the unit. You can get by with adding Freon with an additive to fix leaks and lubricate the compressor. To add Freon you need to access the Low pressure port and jump the Low pressure safety switch for the initial can of Freon.
There are tool loaner programs at the big Autoparts stores which can allow for this process.
These same stores may have electric Vacuum pumps to purge your empty system for refill. If you do not have enough pressure left in your system, outside air can enter. If you are lucky and timely, a refill with Sealant Freon mix after purging the system can restore it.
Every car is a different case. As your car is 10 years old, it may have been leaking slowly for years, or in the last week. You never know until you try finding the leak. Some people just spring forward and trust the Sealant to work. Others use devices known as sniffers or leak detectors before trying to refill the system. Some leaks can be so small or in places with no visual access.
The cheapest way is to use the Sealant Freon after testing the pressure. Use gauges to determine system pressure.
