2005 dyna with fuel inj. Every now and then the bike refuses to start. It runs great for days or weeks and then suddenly - no start. Let it sit for a few minutes or hours or days or weeks and bingo starts right up. It turns over fine, I've checked battery, coil, volt reg., switches, fuses, relays, wires, even the air in the tire and I can't find the problem ANY IDEAS PLEASE?
My '07 was doing that intermittently. Turned out to be the system relay was going bad, causing the fuel pump to go off and then on. It's a pretty cheap part.
Which one is SYSTEM RELAY and where is it located?
Sorry my dyna is an '07 and HD made some big changes to the dyna line between '05 and '07. Don't know where it is on your bike. Do you have a service manual?
Edit: This is what the fuse box looks like in my '07, and #2 is the system relay.

Yep. My 04 did this. If you take the relay into a GOOD parts store they'll be able to cross reference it and save you a little coin.
