'66 Barracuda starts then dies right away

Title says it all. Here are the current conditions relative to the topic:

Pertronix Ignitor II.
New correct for application Flamethrower Coil (msd liquid filled mounted horizontally prior).
Electronic Voltage Regulator Upgrade (car was dying before upgrade was done).
Ballast resistor bypassed.

After it dies, it will start again right away, just won't stay running.
