Dyna issues
I've had zero issues with my Dyna I rode the other day and the next day i went to hop on the bike and it wouldn't start. The second I hit the start button you hear the relay but the bike loose all power after a minute or longer it's like it resets itself and power comes back, push the start button again just a click and all power is lost. Battery is 100% all terminals are okay and everything on the starter is okay. What else can cause this? It's a 2002 dyna fxd

if the battery connections are clean and tight, and the battery voltage is at least 12.6 measured with a volt meter, check for clean and tight wiring connections at the chassis main ground terminal and solenoid terminals.
When you say the bike loses power after a minute, do you mean the engine dies or that battery power dies off? If battery power dies off but comes back again, and the battery is at least 12.6 volts, there is a loose or dirty connection somewhere. A loose/dirty connection point will heat up because of the added resistance, and cause intermittant connectivity
I really hate tracing electrical issues but mostly you need to verify continuity of the circuits involved and verify clean tight connections, not just at the battery but also where starting and charging wiring connects.....a dirty or loose ground connection will cause strange symptoms....good luck

Bottom line for me personally is there should be ZERO continuity between the circuit breaker 12 volt spade connection and ground Maybe TMI but something to test for
EDIT There is a slim chance that the circuit breaker itself is bad....maybe it is opening pre maturely.....my bike 09 FXDF has relays and fuses but no circuit breaker (as far I can find)

You rode the bike and the next start attempt failed? Nothing else done to the bike? How old is the battery? A 2002 possibly with the original rectifier/regulator. Once you get the battery fully charged and tested and the bike started, test for voltage to the battery at idle (13.1 vdc or close) than at 2200 rpms (14.2-14.4 vdc). A good replacement reg. is the Cycle Electric for you Dyna, works a bit differently.

Without knowing what modifications have been done to your bike it is very difficult to pinpoint your problem on a forum discussion, but this sounds like a classic battery failure. If your battery is 3 years old, it is probably time to replace it...

Good luck.

If you haven't found your circuit breaker yet, pull the the electrical cover off, remove the panel secured by four nuts and the C/B is the item with three wires on it. Remember what wires goes to what post.
