Ignition system problem? Help!

Ok finally got some time to tinker with the duster.

1. Choke is all the way open when the car finally dies.
2. Put a spark tester in line and ran it, again ran absolutely great till bam its dead no sputtering just flat out dies. I did notice the first time that the fuel filter was half empty so perhaps it is a fuel problem... Fuel pump is brand new. Going to get another fuel pressure regulator to try my electric pump. Tried it inline tonight but as expected its too much for the carb and leaks by the needle valves.

Spark looks fine the entire time its running so I think ignition is ruled out.
