I first noticed that the speed and RPM dials going to zero and then all the gauges going wild. The alarm that stayed on after they came to life was the low DEF level. Truck kept running with no issues. It might last a minute or two then going back normal. The other night while running down the road same thing started and then all the lights, headlights included went out. 10 seconds later it all came back on. Anyone else have these problems before?
