Wow. Easier to diagnose if it was the entire cluster. The step motor could be failing. Since it does come back to life, I would suspect a bad solder joint. Do you have a scanner that can read speed? You can hook it up and see live data. If it's continuous, the output sensor is good. A bad connection at the cluster will be hard to diagnose. There are companies that specialize on fixing instrument clusters.
