I have a 99 road king classic and it will start and run for about 3-4 minutes then shuts off. Try to start it back up and nothing. 10 minutes later... it starts again and does the same thing. Please help

 

You're in Michigan, bike been stored ? Throw any codes?

 

Bike was stored inside and has no codes

 

You've checked battery connections, they are clean and tight ?

 

Installed new battery and coil and still does the same thing

 

Also checked for spark after it shuts off and there is none

 

yes. New battery and coil pack

 

Replace your 50 amp circuit breaker under the seat by the battery. It has a couple posts and a bunch of wires with circular connectors. Even if it looks fine externally it may be corroded internally. I have spent mucho $ trying to fix a similar problem and it turned out to be a $10 fix. Just do it and eliminate the possibility.

 

Get a can of electrical contact cleaner , great for cleaning corrosion off ground points , connectors , fuses etc . Sometimes corrosion can get into the relays and cause issues like your experiencing .

 

Yes. I would also replace all of the relays under the seat on a bike that age. They are not expensive. A bad relay could intermittently stop sending power to your ECM
