sounds like it was a bit flooded from cranking and then when it caught the petrol in the exhaust ignited and caused the bang. if it happens again i'd leave it a minute, turn the choke off and open the throttle while you hit the starter button to get more air in and see if it catches. it might be losing spark but I doubt it if it's running fine other than the two times you mentioned. it's probably just a bit of a pre-winter grumble :lol
