Most older automotive systems use a dual electronic circuit on the ignition system it has a start and run on the tumbler .. sounds like the ignition sw may have a bad contact in the run ( spray some wd 40 into the key slot and work it back and forth .... the trucks 27 years old so it may have built up debris inside)
