Do not go changing parts as that can be very expensive and still not solve the problem. If the check engine light is "on" then have a shop diagnosis it for you. If it is not "on" then the most probable cause is the air intake and or the throttle plate are dirty.

we had the same problem. we changed the Crankshaft Position sensor, and also the camshaft position sensor. changed ignition coils, and the module under the ignition coil, and still had the stalling problem. an auto mechanic bought it from us and he discovered all that it was was a pinched wire under the ignition module.

Does a 1969 buick skylark need leaded gas?
Yes. I had a 1969 LeSabre in 1980 that still used leaded gas. Any auto store will have lead substitute. Maybe another poster knows if super unleaded is good enough.
