Well, the spark would not have come back if wires got chafed under the flywheel. I’m confused, did you pull the flywheel to re-inspect after the engine messed up/fixed itself? If not, you might just pull the inspection cover to have a quick peek. I hate it when this stuff happens, just leaves you feeling uneasy about the repair. Could be anything, might even have been a bit of carbon fouling the plug temporarily, who knows! I guess I would try to water test it again tomorrow to see if it messes up again. If it messes up again, I would just go through everything with the mercotronic…..
