My question is: Is there a slow death type "normal" failure mode in which

On the other hand I'd rather notget stranded after dark at an airport away
from home with no mechanics around or parts to be had.


A "sudden" failure would most likely be a fracture of the impulse coupler
itself, which does not seem to be where your problem is leading. I'd deal
with it if and when you begin having starting difficulties. However, please
remember that this advice may be worth no more than you are paying for it.
