Fuel Delivery or spark died. Best guess. In no particular order...

Fuel
Compression
Spark
Timing

It has to run. Says so in the book.

Interestingly enough at our spring Model 'A' clinic George showed the fellows an after market cheap set of points bolted properly down to the upper plate.

Spark: Well let me tell ya, the Cooper conductor wrapped to the same rad [arch] as the piece of spring steel would bulge out at low speed and go to ground. Cutting off the spark. Not so bad at higher speeds. Everybody had a chance to see the damaged conductor area where the spark jumped to ground. Like a miniature weld.

Gas delivery: Clean the screen, a lot. Pull the line off the carb. Turn on the gas see if it flows. It likely does.
Carb. Float, float valve, a sticky shut-off from the float valve, main jet fouled, sticky green gelatinous mess from ethanol. Any air filter in the way of air sneaking up the carb.

Gas tank venting? No after market fuel filters in the way of gas flowing.

Timing, warms up points move, spark goes away.
You do have a positive drive between the cam to oil pump, and cam to distributor. Nothing that is suppose to be 'cogged together' just turning with friction after a shaft broke. Honest! I had a 1500 cc VW with a broken crank shaft. It ran but not well. Two complete pieces. Anyway...

Compression. I don't think that's the problem.

I know this is no help. I'd start over with a very very good tune up.
