engine runs but cuts off after a few minutes

Hey, for some reason my car starts and engine runs but cuts off after a few minutes sometimes while parked. Then, when it does not cut off while parked, I will test drive it in my parking lot a few times. Sometimes nothing happens it runs fine, but other times every warning light and service messages like service air bags, service stabilitrak, auto thief deterrent, etc comes up. Then, after that the engine revs up and down, slowly brakes on its own and cuts off, but the energy is still on. After that the car does not turn for about fifteen minutes and brakes are locked. The battery and alternator is good, but I think it may be the BCM because the window does not go up/down, and the doors lock and unlock as well when the warnings messages pops up.
