@rjw69 not all misses are created by your electrical system the miss your describing sounds more like a fuel miss. when an engine gets hot the injector can swell and not send the fuel into the cylinder creating a miss because there was no fuel to ignite. you may want to check the fuel pressure on the rail and check that all the injectors are firing properly.Hope this helps
