I tried installing a Pertronix in my '74 Corvette about 12 years ago. Similar problem to those already described...unreliable performance, would stall or fail to start, I went back to the points and it was fine. Since then if I have converted a car away from points I've used MSD instead with great results. Not sure what Pertronix's problem is, I know alot of people that swear by them, and alot of people who can't get them to work right.
