On my old doo, first the lights would not work. Then suddenly they could work. Ran it like that for several weeks, while trying to find out what the problem was. Then it suddenly shut off the engine. Tried to start - not a chance. Waited until next day, and it started at first try.
Stator issues can cause many strange problems.
I found the problem by attaching a voltmeter with test leads on both wires from the stator to the voltage regulator, and took it for a run. When the problem occured, i saw the voltage reading dropped a lot.
