My 5cyl Hummer battery lost power after 2 to3 days when the car is not used. But this happens just 2 or 3 times a year

Could be a sticky relay or the BCM not going to "sleep" when the vehicle is shut down. Either way a little electrical knowledge will be required to find the exact problem. The worst part is that it isnt a constant thing, so it may be very difficult to pinpoint
