Speedometer stops working after filling gas tank

My vehicle listed above S speedometer stops working immediately after I fill up the fuel tank. Everything else works fine (fuel indicator, cruise control, tach, etc. No error codes before filling up or while driving with no speedo or after it starts working again. No change in fuel mileage or "performance." Only routine servicing and I've never used the car for jump-starting. If I drive the car until the highest fuel bar disappears, then bring the car to a stop without shutting it off, then accelerate again, the speedometer will indicate accurately. Occurs when the vehicle is cold or hot. Any help is very much appreciated!
