Default 69 cranks but no start

I was just driving with my favorite riding buddy,(my 5 year old Grandson) when out of nowhere, the car just shut off. Factory stock ignition system. Cranks fine, Plenty of fuel. No spark to plugs. Replaced coil. Cleaned cap and rotor, cleaned points. Wire to positive side of coil is hot with switch on, also has spark at the points when opening with a screwdriver with switch on.
I checked the Search area and no one else seems to have had this particular problem.
If anyone has any ideas, I appreciate hearing them.

Thank You!!
Rick

Rick, that sucks you and your buddy had a problem. Super dumb question but is the dizzy spinning when you turn the motor over? I imagine it does but figured we’d rule out breakage.

With that ruled out I’d be taking a good hard look at the condenser and the affiliated wiring. The funny thing about a points ignition is the points can and will still arc with a non functional condenser when manually opened. Once you get into a high speed operation IE opening and closing 300 times a minute or more is where it will fail to spark.

Thank You kossuth for looking into this and for your thoughts. Those points and condenser have been in there a while.
Now, time to embarrass myself. I had noticed that the arc marks on the inside of the distributor cap were at an angle at the very bottom of some of the contacts, but I didn't think too much of it. As it turns out, I should have. The Distributor cap was only fastened down on one side. The other side was not all the way down, but the engine would start and run, until it didn't. The cap has been this way since I put this intake on about 5 years ago. I have just been lucky. Sadly, I found this about 3 minutes after asking for everyone's help. Also, I will replace points and condenser tomorrow.
Thank you all for looking and I'm sure I will make more simple mistakes later.

Sorry, hope it wasn't too hard to get the car home.

Like said, verify rotor is turning.

Check spark at spark plug.

I think the dist could have spun putting the timing too far out to run.
