Question about Harley Davidson Motorcycles
Usually one of two basic issues --No gas or no spark. Sounds to like you have something going on with your ignition switch but try checking for spark when it happens first one cylinder then the other. If you have spark then more than likely it is a fuel issue (may not have the float set just right in the carb not allowing enough fuel in to stay running) if no spark then it could be any of several things. Check the ignition switch to see if you have power (without turning it off and on) Does your lights, work, how about your starter switch will it turn your starter over, you have 3 basic positions on your switch --ACC, off, On sometimes the connections in the switch get corroded. If lights and starter work then the next thing to check is the on and off switch on the Handle bar. Sorry it is best to track one item at a time and there are some good online mechanics that can help if these suggestions do not help

If the spark is fine, then it is not wiring. It is going to more than likely be fuel. Try spraying a little starting fluid in the air filter. If it starts, then you will know that it is fuel. Make sure that the carb is getting fuel from the tank. A lot of times the filter in the tank will get plugged up. If the bike doesn't start with starting fluid, then the problem is not fuel and will have to be either the timing is off or not enough spark. The spark should be blueish purple.

Hello and welcome to FixYa!
If it backfires then you definitely need to replace the ignition coils. Don't forget to replace the plug wires as well for if it's worn out, current tends to jump which may cause current supply irregularities. Once replaced I believe you'll be good.
Hope this helps and thank you for using FixYa! Have a good one!
