I was driving along on the expressway and noticed my dash go dark and completely shut off. Cars still running mind you. Odometer, Speedometer, Gas Gauge, etc...all shut down as if the car was turned off. This occurred for about 20 seconds and then it popped back on. It couldn't be more dangerous considering I had no idea how fast I was going for that 20 seconds. Now it's occurring more frequently. No faults pop up just lights out. Any ideas what the issue is? Appreciate the feedback.
