Thanks to all that have responded.

Yeah, generally a bad cap will just make it run really rough. I had an experience (different model year - 1971) where we were camping on the beach and the salt air got to it. I put in a spare set of points and got it started but it still ran awful. About 10 miles down the road it smoothed right out, when the engine heat dried it out. Finally got to a store and bought a new cap/rotor but didn't put it on right away. Same thing: ran rough for a couple miles until it warmed/dried out. Later installed the cap/rotor at a campground and it was fine after that.
When my 89 just shut down going down the road, it was the ignition module in the distributor.
