Spider in fuel cap vent hole blocking free flow of air. Yes, I have
seen it bring a Healey to its knees. Hank

    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).   
  The last 2 shutdown times came when she was idling waiting for a
light or for a car to pass.  
  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.  
  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.  
  Thanks  Tom
