I have the same issue. Except mine seems to happen more often. Driving down the road it will bounce around between current rpm's and zero. Also my obc turns off when the tach goes to zero. I'm guessing its some kind of grounding issue. Maybe located outside of the car. I've checked the main ground under the dash and it seems to be in order.
