Perhaps you have a problem with heat or vibration at your ignition box or you have an unreliable distributor brand or any number of possibilities. The point being that points ignitions are far less reliable than a good electronic system. I would look at your system in total, not just the brand, but the quality of the wiring, how it's routed, how it's shielded, where and how the box is mounted, etc, etc. True, spark boxes do fail and there have been some distributor quality problems, but overall, a good electronic ignition should beat grandads points every day of the week and twice on Sundays in terms of reliability.
