No electrical power in cabin while running

My car has been acting up recently. At first when I started my car, nothing in the cluster, windows, air conditioner, cruise or radio would turn on. Within a minute or five everything would kick on all of a sudden either while running idle or driving down the road. Currently no electronics have turned on while the car is running despite being on for more than fifteen minutes. Here is the weird part. I checked all of the fuses to the cabin electronics and everything is fine there. If I put the key onto accessories, the radio turns on along with oil, security, and battery lights. Once I start it, everything shuts down and only engine light is on. Headlights will only turn on manually. Turn signals work also. Just no power to anything in the cabin. What is going on? This has me completely stumped.
