Speedometer occasionally quits and starts back after it is parked

What is your question?

The speedometer registers good for several days then it will quit working. You can park for as little as 5 minutes then it is correct. Speed sensor was changed but it still does it. Any suggestions?

What makes this problem better or worse?

Nothing seems help

How long has your 2010 Ford Ranger had this problem?

I purchased the truck 2 weeks ago and drove it for 4 days before started doing this
