A week or so ago I posted an odd-seeming problem with my 84 Digifant inline
ABA motor...failing to restart after a long coast downhill, but after
Cycling the ignition switch a few times, it'd go again and run
perfect...till another long downhill... intermittent, too, but increasingly
frequent.

  Quite a few people responded with ideas, ..many of them things already on
"my list" ....but one nailed it with a faulty idle control module...a part
I didn't know existed.
.Then I found one in my spares...labled "ignition control module"..
Stuck that in ...1000+ miles and no more problem... Thanks all
