I have a similar issue with my 2011 etec. The speedo, tach and odometer stop working periodically, maybe 5% of the time. When it goes out while driving, I will hear a beep and they gauges come back to life. All other electronics (lights, hand warmers, etc. ) work just fine all the time. I've taken the gauge pod out, unplugged and greased the plugs and plugged it back in and it made no difference. Dealer told me that they couldn't replicate or diagnose the problem.
