Question about Harley Davidson FLSTC Heritage Softail Classic Motorcycles
Bikes runs great and idles with no problem. Occasionally it loose power and shuts off completely. After I pull over I can re start it within 2 or 3 tries of the start button and again runs fine. It happens on the Highway at 70 mph and at traffic light at idle. It appears to be a little more frequent when the bike is warmed up. Thanks Roberto
Just a guess, have you checked the ignition coils? One may have a crack in the wound wire. When it warms it opens then closes when it cools down. There are a number of things that can cause your problem, but I would start with the ignition system.

The first thing you need to check is the air filter. Sometimes critters can get into the airbox when a bike sits for awhile. Sounds crazy, but it has happened to me. If nothing is blocking the filter, give it a quick clean since you have it out.
Next things to check:
Improperly adjusted fuel level
Clogged or loose main jet
Faulty fuel pump
You may not be able to check these on your own, but these are the next likely culprits.
Hope this helped

Check for vacume leaks first. Rubber lines..gaskets to carbs ect. Also remove and blow out your fuel line to tank and change out filter. Hope this helps.:)

This sounds like an air leak ahead of the carbs. Air that hasn't gone through the carbs is leaning the fuel/air mixture. Cracked rubber fittings, "O" ring seals, gaskets, and clamps between the carbs and the cylinder may not be sealing well enough. Note that a bad head gasket, bad valves or loose spark plug can also let air enter. The problem will get worse as time goes by. Do a compression check to check the valves.. Burned valves and cracked rubber seals are normally the culprits. Usually, all the valves need is to be re-lapped to provide a fresh face on the valve and valve seat.
