2002 Low Rider Dies when hot

I have a 2002 Low Rider that when it warms up it will die. Let is sit for 30 minutes or maybe shorter, it will start again. The last time it cut out on me in my driveway, I pulled the plugs and checked for spark. As I suspected no spark. I purchased new battery, ECU & coil. No difference still no spark after it gets fully warmed. Usually it takes about a 2.5 mile ride. I checked for loose ground at the battery, it looks good. The bike has always ran with no issues. I did not ride it much last year and it sat through winter this year, so my point is, it just started doing this after sitting for some time in the garage.

Maybe it's pissed at my and I don't blame it. I should show it some more love.

Any ideas all?

Thanks,

Steve

Quit throwing parts at it. Get the Harley electronic diagnostics manual and follow directions.

Don't go by looks. Take all the connections off and clean them. You'd be amazed at what can hide in 17 yrs.

Check the wires at the starter where the B+ attaches. There is a smaller wire that sometimes breaks off the terminal.

Sounds to me like the CKP is taking a shit !
Wonder if the bike has any stored codes ?
New battery, ECM and a coil. Well there went $500 bucks !

OK good advice on the grounds, I'll look at that today more closely.

Does the 2002 FXDL have this diagnostic program, or is it just on newer models?

Step 1
Turn the key in the ignition to the "Off" position. Turn the "Run/Stop" switch to "Run." Push and hold the odometer "Reset" button. Hold the "Reset" button and do not release it yet.

Step 2
Turn the key to "Ignition," but don't start the engine. Release the odometer "Reset" button. Wait for the odometer to indicate the bike is in diagnostic mode by displaying "Diag." Push the odometer reset button and then release it when you see the "P" in the menu selection flashing.

Wait for the bike to complete the diagnostic of the electronic control module and the ignition control module. Write down the codes that are displayed after the diagnostic is complete. Code PO 374 indicates a failed or faulty crank position sensor due to a synchronization error.

Bingo, failed CKP !
