Over the past year I’ve had four instances of the engine quitting
while driving. If I wait minute or so, it
restarts and runs fine for weeks or months.
Attempting an immediate restart when coasting to a stop never works.
Typically quitting happens within a few miles from the
beginning of the drive and has never happened after more than 10 or 15
miles. The last time it happened within
two miles. Also, I thought I heard a
small backfire when it quit. When it quits there is no bucking or loss of power, just a clean stop.
Aside from removal of the air pump and most of the emissions
stuff and addition of modern electronic ignition, long before the problem
started, the engine is stock.
I recently refurbished the fuel vapor system and checked
that all tubing was clear, tested the anti-run on value and tightened rubber tube
claps. The quitting predates this work
and the most recent incident was after this work.
Does anyone have ideas on what needs fixing or how to
diagnose?

Roger, Had similar problems. George Van Horn replaced the coil (it would get hot while driving) and the condenser and rotor. Steve

Keith, hi my name is Gerard I have a 79B, I am no expert but I would like to offer a suggestion. You said you were removed some of the Emission control system? When I first got my B, two things cause the engine to stop abruptly one was a vapor lock generated in the fuel line near the carburetors(my Zenith Stromberg was replaced with twin SU HS4's) The second and this is my particular theory could be a fool the anti-run on valve. There is also a fuel cut off valve under the drivers dashboard, which is designed to shut off the fuel flow if the car flips over. Validate the operational condition of these items it may be a place for you to start. Good luck keep me posted and let me know what happens. Gerard ........ gdangelo6118@...
