Looks like the "contact" on the switch is bad and "the spark" on the everyday use are worn it even more, you are right its time to replace the ignition switch.
I saw some issues with the caravan switches, it worth to check if is any recall on them, anyhow I ll check that for you and I let you know
also if you need some guidance to replace the switch let us know and we ll pull out some schematics.
BTW thanks a Lot for your donation!
Let us know and good Luck!
