Thanks Jeff. After scouring the newsgroups, there seems to be numerous
problems that match to the symptoms. Most folks say the majority of
problems are ignition circuit related, unless you suspect this in which
case, the problem is fuel related??? The first three in the list are
ignition related...

1. Arcing in the plugs, secondary wire, or distributor
Inspect/clean replace
2. Coil breaking down
Swap
3. Shift interrupter, cable tension
Disconnect and test underway
4. Fuel accelerator pump/varnished carb
Replace/soak
5. Vacuum in the gas tank, lines
Remove cap to test, clean vents
6. Water, debris, bad gas
Check filters, fuel seperator, clean or drain

I've already done 2 and I can probably test 3, 5, and 6 without messing
anything up. After that, I'll probably get some help.
