I had a 91 D250 Cummins pickup. The speedometer used to do that every once in a while. The way I fixed it (don't laugh) was to take my hand and slap the dash right above the speedometer.... HARD ! It would be good for a while, but would always do it again, usually after a few weeks. Give it a shot.... - intentional play on words.

Assuming it still uses the old rotating cable system, check the connections of the speedo cable behind the instrument cluster and into the tranny. It may have come loose, or the cable may be sticking/frozen.
