Ditto what Mac said I lean towards starter with a twist…, if it clicks every time you twist the key to start-your hearing the solenoid try to activate- however the brushes on the starter motor my have landed on a “dead” spot in the motor windings. the repeated attempts to click the starter is getting that motor twerking

and moving a small amount until it reaches a good contact point. And the of course does what starter do… might be time for a new one.
