Default 81 ironhead no spark when cold

Got a weird one for you guys.. got a 81 ironhead 1000 I've owned the bike for about 3 months when all of a sudden this issue starts.. when the bike is cold and it has set for more than a day bike will get no spark from either plug the only way that it will fire is if you keep turning it over until the batt is almost dead then it will pop a few times then time to get that batt booster. After you attempt will the booster pack for about 10 mins the bike will start and run perfect you can run it for maybe 10 mins then shut it off and it fires right up the engine just needs to be warm wth is this thing deal I'm stumped.. ps does have an accel ingnitiom module
