My first 2010 Bushnell had that problem. I called Trailcampro, where I had purchased it from, and they replaced it immediately. The replacement camera has never had that problem. The run-away problem was a common problem, especially on the first batch of 2010 cameras. You might try turning down the sensitivity, especially in colder weather. I'm not sure if this will help but it's worth a try. By the way, welcome to the forums!
