97 FXSTS (Softtail Springer)
Still Trying to figure this out. Believe me, you guys and gals are smarter then me so help a guy out.

No spark to plugs.

Starts great. Runs for about 5 minutes idling, then dies. No spark.
Lights are still working. so has power.
It does not putter like its loosing fuel. It instantly quits.
Let set for a few minutes (5-8 minutes) then has a spark and starts.
Rode it about 3 miles to a exercise facility and stay an hour. Came out, started, riding home it looses power for about 2-3 seconds as I coast along then takes off and I make it home. This is consistent each day.

Changed coil but still died.
Replaced the ignition module. no help.

Ideas please.

I've been told that a bad stator can cause this – any thoughts on that guys or gals.

 

You didn't mention that you changed plug wires.

Also, is it possible that there is a loose ground wire somewhere and it's vibrating loose?

 

Everything stock on rhis bike, other than the things you recently swapped out?

This is a carbed bike?

What ignition module did you install? What coil?

​​​Other than the cutting out itself, why do you think this is spark related? What tests have you run?

If everything is OEM, my guess is ignition pickup inside the cone on the right side of the motor.

 

I had a similar problem that ended up being a loose ground wire under the seat.

 

Could it be the stator?
