Most likely a worn electrical ignition switch. There is a steel rod that runs from the key cylinder to the electrical part of the ignition switch. As you turn the key the rod is pushed down and activates the different areas of the electrical switch. The switch is usually mounted on the top of the steering column with four small screws. It also has some amount of adjustment. It's possible it is just loose and/or needs to be adjusted to work properly. You'll probably have to take out the bolts holding the steering column up.. usually two bolts but maybe four. Let the steering column drop down to gain access to the switch.
