Headlight Switch problems of the 2011 Dodge Ram 1500

After passing a slow moving vehicle on the highway, my truck shut down. The engine cut off ,dash lights and park light started to flicker erratically and the headlights went off. I managed to pull the vehicle to the side of the road. In order to stop the lights from flickering I disconnected the battery (they flickered with the switch in the off position). As the lights flickered I could hear relays clicking under the hood and dash. After waiting a while I reconnected the battery and all systems came back on and I was able to start the truck and drive it home. The dealership will not be able to check it out until wed the 18. All systems seem to be normal. I have to go to work . I' m driving it 60 miles round trip everyday.
