    Like I said hope I’m wrong but they don’t typically fail that way. We shall see.

      I’ve tried to think through this using several problem solving methods - one is ‘what was the last thing I changed before the problem started?’

      Two things-

      Distributor was rebuilt and recurved by Advanced during my engine rebuild, and he installed a new condenser on the plate in the build. The rest of the ignition system is all the same parts as before. That made me think the condenser could be an issue.

      I installed a new radio just before the issue started. Not much of a change as I was trading a Pioneer for a Pioneer. This morning I pulled the radio and looked for any connections that were loose or exposed. I insulated the connections on the heater switch (should have done this long ago). Also found one purple wire connection loose that I’ve never known the use for (assumed interior light). It was insulated/tied off previously, but I re-did the job.

        You may want to try these condensers form the Distributor Doctor. Sounded good to me so I bought a couple....one went right into the distributor and one on a spare points plate.

        ut beware...if you think you'll get a yellow wire upgraded condenser from TRF as advertised in their 'TUNE-UP" catalog, you may not.....you may get a blue wire condenser which they said was 'just as good'....maybe, but the DD has the real thing.

          I am experiencing similar on The Green Hornet, my sons car, a 73 also

          So far changed:
          Condenser
          Coil
          Fuel Filter
          Cleaned all brown wire connections.

          Feel like I am now easter egging..

          Next up is:
          Ignition switch check
          Fuel Pump.

          Car cuts off. I need to drive it and experience the actual symptoms.

          Just got his rebuilt dizzy back and need to install it anyway, but one thing at a time to see what the heck this is....

          Not sure what Jeremy's final issue ended up being.

            As part of my rebuild I put in a new electrical system. Part of that entailed using some parts from the old one and I was amazed at how much corrosion and oxidation I found in sections of the harness, even behind the dash.

              Did it again today after the boy washed the car. Saw wetness along the brown wires inline the pos battery cable.

              Son said he cleaned them, but I cleaned them well, all corrosion and dried and tightened.

              Finally nailed it.

              Geez!

                  I know you did! and I jiggled the cables before and had the boy clean them.

                  Well, apparently I trusted him and didnt check his work.

                  Not a good job, as I confirmed today after removing the cover and digging in deep and doing it right and tight....

                  Still green corrosion on some terminals and lugs.....

                  C'mon boy!.....

                    Yeah I got some of those younguns like the one that helped me rebuild the car. They got no idea what clean is, I had to show mine quite a few times by having him show me his “clean” before putting something back together.

                    As Reagan used to say “trust but verify”

                    Hopefully you got it.

                      The small wire that runs from the coil to the dist. if famous for developing an almost invisible break and causing an intermittent miss.

                        I had this happen, and found it was a bad connection in the ignition switch itself. A good cleaning and some dielectric grease fixed it.
