This sounds like the BCM is going out, but to be sure let's run a CAN scan which will have codes relating to the problem. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.
Here is a video to show you how:

If you do get codes for the BCM here is the location, I would unplug it and then plug it to check the electrical connectors for corrosion. If that looks okay, you can get a preprogrammed unit by searching Google or Ebay. Here is the location of the BCM. Check out the images (below). Please let us know what happens.
