73 valiant runs good then randomly dies
IF YOU CAN JUMPER WIRE THE IGNITION AND IT RUNS then there is likely NOTHING WRONG with the ignition system, including the distributor, the module, or the ballast.
Might be bad connections in the (infamous) bulkhead connector, the ignition switch, or the ignition switch connector. ALSO Redfish has pointed this out several times........DOES YOUR car have a WHITE connector which hooks the engine harness to the rest of the firewall harness? This would be the ONLY white connector there in the engine bay. Look it over good, disconnect it, and examine the terminals.
YOU CAN DOWNLOAD the 73 service manual...........which came from the efforts of guys right here.......from MyMopar

From the same site above you can also get aftermarket, "somewhat simplified" wiring diagrams.

SlantSuxDan thinks he knows everything about these cars BUT THE FACT is that this "MAD" article is a VERY good overview on some inherent problems AND IS ONE WAY to deal with them THAT WORKS, inspite of his opinion that "they are a bunch of Chevy heads"
Catalog
Of special note in the article is the simplified diagram which shows SOME of the problem areas in these old girls
The "list" of problem areas in no praticular order:
Damaged bulkhead terminals from years of corrosion and over amperage, as well as too-large alternators
Loose or defective terminals AT the ammeter, as well as internal problems in the ammeter itself
Bad terminals in the ignition switch connector
The ignition switch itself
In rare cases a bad "welded splice" In my lifetime, I can document about a dozen of these. The first one I PERSONALLY FOUND was in about 1970--71, in a friend's 69 Plymouth RR
The above mentioned "if you have it" the white engine harness connector
