I have an 03 FLHTC with 33000 miles and is stock so far. The bike is carburated. I have an issue where I am riding down the road and after the bike warms up it dies suddenly.Allthe guages work but the RPM's drop to0. I checked to see if I have spark and I have none. I replaced the Ing coil. I replaced it because I was told to. It still dies. I ohmed out the plug wires and right in range with what the service manual says.
I have checked the main breaker when it happenes and have power to both sides. it turns over just no spark. Let it sit for a bit and it will fire up and run for a bit. What I would like to know is how do I check the map sensor, Crank sensor, or the Ignition modual. Will Hd test the ign mod? Is there a way to test it?
Is there anything else that I am overlooking? Any help in testing this stuff would be great. I talked to the HD dealer and they are booked for 2+ week before they can even look at it. I would rather not wait that long. Thanks for taking your time to read this. I hope some one can answer my questions.

I would replace the ignition modual (little black box with two bundals of wires coming off of it.

 

I just wanted to let everyone know that it was the crank shaft positioning sensor that would cause the dieing issues. It was cheap and easy to fix.$55 and 15 min later i was done with it. I am a little pissed at myself that I didnt replace it right away. Any how I just wanted to thank everyone for their help.

Thanks for the solution post. Its nice to get the answers when a problem is fixed.

 

Yes, one thing I found while researching my problem was the Cam sensor won't cause the bike to die! Mine ran with a bad one, just gave me a CEL. However the dealer I talked to, and someone on here said that a Crank sensor would disable the bike. The Cam sensor set a code on mine, and could be pulled by jumpering two pins on the plug under the seat, (The manual told me how to do this)

Glad you got it fixed, and I need to get mine rolling again, (But when it rains, it pours, because my Powerstroke just toasted a turbo last week, so I am in dire straits with vehicles! )
