Was our driving a while back, engine purring, and suddenly she shut
down. Let it sit for a while and she would start and run for
a while--then shut down again. I tried many fixes which I
will list below. Several times after the fixes she went for
miles and miles and I thought I had "fixed" it.
Nope-----yesterday----it was AAA tow time once again (3 times this
year). </div>

The last 2 shutdown times came when she was idling waiting for a
light or for a car to pass.</div>

So here is what I have tried: * new coil * new voltage
regulator * new fuel pump * New ignition switch *
Blew out the fuel lines * pulled float bowls and cleaned them (no
debris inside) * Pulled the distributor plate out and cleaned
and oiled it * disconnected the wire leading from the battery
cutoff switch to the coil. * bypassed the entire battery cutoff
switch * replaced the Pertronix with a new one * checked all
the sparkplug wires to make sure they were on properly
* replaced the distributor rotor *Replaced the distributor
cap . * checked the small ground wire inside the distributor to
make sure it was attached properly.</div>

All this----and STILL o joy. I'm really out of ideas at
this point. If anyone has any ideas for me to check please
share them.</div>
