[Shotimes] Cutting out???

[Ron Porter]

FWIW, I probably had the first crank sensor to go bad back in '91 (well,
with the Prodigy BB as the only source of SHO info at the time).

It first started with stalling for 10 seconds or so, then the timeframe
gradually got longer until it was a 1/2-hour in hot weather. Since the
dealership fixed it by accident, after replacing everything else in the
ignition circuit, this has been the typical failure mode for most folks over
the years.

For those suggesting crank sensor, the last time it would simply quit, and
not start for 1/2 hr. or so until it cooled off.  Very different symptoms.
But its very possible that is what the problem is.  I think I'll swap a DIS
in and see if that fixes it before I dig into the front of the engine.
Thanks everyone for the suggestions.
Mike
