Have you removed the #1 and #4 plugs to check for spark? I've experienced where the spark plug wire terminal tensioner was loose and that created a miss, but it was always present. Did you hear a snap when the spark plug boots went on? Did it smoke white at all? What if you remove the cap from the radiator? ...will it then go longer than 5 minutes without missing? I would check for a blown head gasket.
