2003 roadglide from time to time take a ride park the bike but if indeed to move it right away she cranks but no spark. So won't start till she's cool down. No oxy sensors on her so any ideas?

[windjammer]

Do you have a tuner or is it stock? Once upon a time I had a power commander that did the same thing.

If no Power commander installed, next suspect item is the crank position sensor.  Any codes?

If I remember correctly, the 2003 model didn't have a Maxi fuse but rather the old circuit breaker which was prone to thermal failure.  Since your problem seems to be related to temperature, I'd check the main circuit breaker and replace it.  I think it was a 50 amp breaker, someone like Twolanerider would know for sure.

It has a se race tuner and had the circuit breaker problems m in the past but it kills everything not just spark couple years ago did get a code on the ecm but not sinse.  And replaced the crank position sensor two years ago

  Yup my 2003 had a 40 amp breaker dealer replaced it with a 50 amp still would shut down, he ripped that out and put in a 40 Maxi problem solved till traded in 2009

I experienced your problem some years ago.  It turned out to be a failing coil...

[Twolanerider]

It is a 40 amp breaker. They will behave as Scot suggested. Though perhaps the absolute regularity you describe might be a little unusual.  Might also question the coil and the crank position sensor. Remember too that vintage bike still has the cam sensor and those were nortorious for failure.
