383' shuts off' issues, I tried praying, no luck

no i'm not sure about fuel or ignition , just looking for ideas I may have over looked. Old points ignitions don't havea real hot(blue) cranking spark, and I hope today to get someone to start it and let run while I hold the coil wire off the distributor cap to see if it looses spark, that's the only way I know here by myself how to test that. thanx, Crossy

You can always get another distributor cap and drill a hole in it to check for spark between the rotor and the tower. I'll admit I'm not sure where exactly to drill the hole, but I've read plenty of posts where this is done to check rotor phasing. This would allow you to view the spark as the engine is running without an assistant.
