You are not kidding...definitely worth the $100

 

i had a issue somewhat similar to what you are going through on a 01 ultra. check to make sure that your sytem relay commmonly know as fuel pump relay is not losing its controlled ground from the ecm. im not at the shop so of the top of my head i belive the wire is brown possibly brown and black, it will connect into your relay, put your volt meter on the postive terminal on the battery and the controll gound (brown wire), while bike is running, you should get battery voltage. if not look for open wire. note that as soon as the bike quits turning over you will lose the ground.

also will the bike restart after it dies?

 

Is the fuel pump "spinning up" when you turn the key on?

 

Do you loose all power when this happens?

Could be the main breaker. Problems with them back then.

 

I don't think 13 vdc is enough. The voltage at the battery should be above 14. There is also the relationship between amps and voltage. If your voltage is below 14, then the regulater and/or alternator is at max capacity on amps and still can't keep up as seen by the lower output voltage.

There could be many reasons including what others have said about connections, breakers, etc. Another item to consider would be an oil pressure cut-off, if your bike is equiped with one. The ECM will shut off the motor if there is low or no oil prssure after a few seconds on some other bikes and cars.

Sounds like it may be time to invest in the service manual.

 

The Voltage SHOULD be at 13.2 vdc @ 1000 rpm, and 13.8 vdc @ 3000 rpm.... these ar mins...

HD bikes do not have an Oil Pressure cut-off... It will run with no oil pressure...

 

I will check out the system relay that you suggest. Should I measure the voltage at the ECM or at the relay? Where is the relay located?

To answer your question...it won't restart unless I turn off the ignition for at least 6-10 seconds. (after I can hear the very soft click of a relay or something) Then it will restart but run for less time on the second start.

 

That seems like a fuel pump issue.

 

Yes. It does and it does after it dies once but won't start. The pump is definitely doing its part.

 

No, I don't lose all power. The headlight is still on and lights on the speedo, etc. The only thing that goes is the spark.
