I had the same problem with my 2007 wideglide. It was a corroded negative battery cable. The ring terminal and wire (where the negative wire connects to the frame) had so much corrosion that it was making intermittent contact.
Another possible issue could be excessive oil blow by in the intake. It causes problems with the IAC motor and makes the engine cut out.

I have a 2006 Dyna 88' twin cam. Your answer sounds like the a something that would give me the same problem. Except mine is a later year and model

Shouldn't be the same on a dyna. It wan only touring bikes (ultras mainly). They had a 30 AMP (if I remember correctly) circuit breaker on them, the breaker would overload and trip killing the bike. Since the circuit breaker was auto re-setting after it cooled off it would reset and the bike could be started again and be fine untill it heated up and tripped again. The service bulletin had HD replace the 30 AMP with a 40 Amp and all was good. Somewhere around 05 or 06, maybe 07 they started putting maxi fuses in them and ditched the circuit breaker.
Does your bike loose all power? I.E. headlights and everything shut off? Or does the bike just shut off like you hit the kill switch? If it looses all power it could be a bad ignition switch, does yours have a keyed ignition or the **** on the tank you turn?

Loss of power
I just recently purchased a 1996 ultra classic with 8400 miles on it, I have now have 9400 miles on it. Today while riding at about 65 mph everything shut down. Tach went to zero, then within a few seconds it started back up. I rode about 100 miles an was riding after dark an it shut down again. Just like the kill switch had been turned off. All the lights went off, I turned off the passing lamps and radio an everything came back on. Do you think it's the circuit breaker.
Imhad same symptoms last two rides at random. Happened when coming to a stop.. Checked ECM codes and nothing read with PV tuner. Where is temp sensor located and wouldn't a code be thrown if it was temp,sensor ?
On any bike that actually is tripping the breaker, the eyelet will most likely need to be replaced. If you have one that trips, touch the posts - you'll quickly find which eyelet to replace.

My 2009 Sportster 1200 custom was stalling out as well intermittently. There was an 'O2' sensor code thrown. Changed that...Still stalling.....Tech saw some 'iffy' looking wiring behind the run switch....changed that.....still stalling. Turns out that the bike had not been run much before I bought it in March of this year (3000 miles). Took the tank off and the fuel pump was corroded out and a ton of rust in the tank. Loaner tank now while the other is getting recoated and is GOOD!!! Took a while but I have a reliable bike now not constantly worrying about it dying out on the highway!! Just thought I'd share. Another possibility for someone with the same issues!! Cheers...Jaycee
