The condition you describe sounds very similar to what I experienced about two years ago, but much worse. You most-likely have an issue with bad gas, like all of the other replies are stating, but I suggest that AFTER you get fresh fuel in it you perform the throttle position sensor reset: With the motor off, and the key on, slowly twist the throttle from full closed to full open slowly, and then back to full closed, slowly. Repeat two more times. Start your motor - that's all there is to it.
Good luck.
