64 Dart 273 Engine Vacuum

It has Fuel, it has spark and it has compression.
Bingo, I found the problem and it is the Distributor Condenser.
Never saw one the would start and run for 20 second and the crap out.
Most of time just bad and will not start at all.
Thanks for all the help and input.

The new condensers now days are bad news. Buy a few from @halifaxhops. He sells new old stock ignition parts. The good stuff.
