Default No spark for few minutes

Hello.
My 1980 FXS80 Low Rider - engine stops every few minutes.Fuel line is OK.I replaced petcock and every part in my S&S super E carb.Month ago pistons and all gaskets.When it is cold it starts in 0.5 second but after few minutes stops and then after few minutes starts again for 2-3 minutes and stops.When trying to start engine I smell fuel.In the dead period there is no spark and my 1 month old new plugs - specialy in front cylinder are black like old ones.What can be a problem?Ignition?Coil?
Any ideas?
Thank You

Sounds like the coil is bad. As it heats up, it stops working...
