It takes 3 things to make an engine run. Compression (ignore spelling, I'm drunk), spark and gas.

Generally you do not lose compression and regain it to sometimes run again. I think you can eliminate that.

Gas. That's an easy one to check. Are you getting gas to the carburator? You have a Holley so that's easy to check.

I'm tending to agree with Jim that it's in the ignition system. Pull a plug wire and hold it to your...... Never mind. We don't want to hurt you.

Stick a screw driver in the plug wire and put it within .10 inches of a grounded steel object. Have someone crank it over and see if you get an arc. If not, that is the problem. We can start to narrow it down from there.

Hell, if worse comes to worse, buy some beer, provide an address and I'm sure some of us can come over and help you out.
