I, too, agree that a pro is the best answer, but while you're waiting, you might want to check a couple of things. With the power OFF, check to see that the fan is turning freely by hand. If it takes any effort to turn it, then the bearing is seizing. Next make sure the condenser is completely clear of any obstruction, shrubbery growth, grass clippings, etc. Follow that up with a thorough blast of water from the garden hose nozzle through the condenser fins. Now power up and see if you have increased your run time. Short of an ammeter and other goodies, that's about all you can do.
