Does Anyone See An Issue With Splicing Ign 1 & 2 at Harness?

The probable causes are the ignition switch, the ignition switch connector, the bulkhead connector, AND SINCE YOU DID NOT MENTION what you are working on, some years have the ill advised white molex style connector to separate the engine harness, and of course "bad connections" from spliced wiring.

IGN1 GOES DEAD during cranking. It must have IGN2 which supplies power DURING cranking. IGN2 is a separate circuit/ switch contact from the "start" circuit. IGN2 was originally intended for ballast resistor equipped cars, as it pushed full battery power to the coil+ during cranking

Don't discount it could be the MSD itself, a problem in the distributor, or even the main power feeding the MSD.
