2004 Speedometer intermittent

2004 Limited - The speedometer will, occasionally start to display incorrect speeds, usually way too slow, like half or less. Usually shutting down and restaring the car will correct the speedometer display. Mainly happens only after driving the car for a while (20 minutes or more) but may not happen at all. However, the heads-up display shows correct speed even when the speedometer is off, the oodometer appears to be correct.

Any ideas?

Chances are that the step motor for the speedo is failing..

Stepper motor replacement solved the problem!
Thanks
