Cross-Country Road Trip in a '68 Barracuda

I had something similar happen leaving Albuquerque NM in my old ‘67 Nova. The cheap rebuilt distributor had the wrong points installed.

wonder if it’s an ignition issue. The elevation just enhanced my issue. Is it points ignition? Have a timing light?

Anyways...

From now on out you need 4 gallons of backup water.

consider pulling spark plug to find one or two that look different
