This definitely sounds like an electrical problem. Check all the
wires and connectors for the ignition for good contact and no chaffed wires
that might be shorting to ground. Be sure to check the blue/white wire
that goes to the starter solenoid for good connection. The ignition
switch might be the problem(?). You might want to temporarily disconnect
the Tach to see if it is the cause. The distributor assembly has to ground
through the hold down plate and the bolt to the engine and the engine
through the ground strap to chassis ground, be sure this is a good
connection to ground.
The distributor wobble should not be a factor, they all wobble some,
but never rule it out until you are absolutely sure it is not causing a
problem. Usually it's the bushings in the distributor that wear. There
are 2 bushings in the distributor; B8QH-12120-A is the major bushing and is
still available from Ford in a box with 4 pieces. I have seen 2 types of
lower bushings; one is the same material and OD as the B8QH bushing, you
just need to machine one of the B8QH parts to length. The other type was a
rolled sheet of perforated bushing material.
This does not seem to be a fuel problem but check your carb bowls
the next time it stalls to be sure.
May the force be with to cure these hiccups. :)

Subject: Here We Go Again
I've posted before about my once in a while intermittent ignition
problem when the Tigerr stalls, usually from idle (about 900-950 RPM) ,
but ocassionally I get a "bump" at high speeds,. It has also sometimes
stalled at high speeds. In the past, this usually happened when it's hot
out (85-90 and above), with the air conditioning and the stereo turned
up full blast. It was suggested that my four year old 60 amp. alternator
wasn't up to the job (letting voltage drop below 12 volts to the
Pertronix Ignitor II ignition?). So...I installed a 100 amp alternator
last week.
I found out today the alternator is obviously not what caused the
problem. Only about 80 out, water temperature not much over 170, the car
stalled on me several times from idle, then bumped three or four times
on the freeway today. It doesn't seem to happen under full
acceleration, but is more likely at cruising speeds or idle.
I'm getting behind the dash tonight to see if any wiring to the tach, my
new voltmeter (which just gets its voltage from the fuse block so it
shouldn't interfere) or the ignition switch (when the car "bumps" or
shuts down, it's like someone just briefly turned the key off and back
on, or completely off when it stalls) looks funky.
Maybe another clue: my distributor shaft is worn and wobbles a bit.
Could this be a factor? It's an old Ford dual point I converted to the
Pertronix.
On the other hand, I don't think I ever had this problem (other than
vapor lock on my previous Tiger) before I installed the Pertronix. So,
maybe I should just get it over and put in a new disrtibutor. I'm
thinking of the MSD "Pro-Billiet" unit, which has the ignition module in
the cap.
Any new opinions on what could be again happening? Could it be the fuel
pump? I'd hate to spend the bucks for the new distributor and have the
same problem on the way to SUNI.
Thanks.
