I only mentioned lightning strikes as i'm very familiar with the issues they can cause airliners, from nothing to whole electrical resets, that take a few minutes to sort out. Which is fine if your engine is independent, but it makes me worry if you on top of the electrical problems also had the donk stop until everything sorted itself out. That single 15amp breaker also seems a bit of a failure waiting for Murphy to have the once over. In any case as long as pilot is well versed in picking paddocks (or resolving said problem) then no issue. In theory cars run on for years without electrical issues as well, so I should be more trusting, but something about boats and aircraft makes me think twice.
