There are many reasons, depending on the year. The most common problem in F-150 (also F-250, F350, Explorer and Expedition) model years 1999 - 2003 is caused by defective solder joints on a circuit board that passes the odometer signals to the dash display.
The repair is expensive if you take it to your Ford dealer because the dealer's method of fixing the problem is to replace your entire instrument cluster. You should expect to pay around $600 if you decide to have the dealer replace it.
You could also replace your instrument cluster with a used instrument cluster, but you would probably have the same problem with the used cluster. You would also have significant additional costs in having your ignition keys and PATS (Passsive Anti-Theft System) reprogrammed to work together. Your vehicle would not start until the reprogramming was done.
The practical solution to this very common problem is to simply repair the intermittent odometer yourself. The entire problem can be eliminated in about an hour using only simple hand tools and a low-wattage soldering iron.
