Losing power
Any help will be appreciated. I have an 03 Electra Glide Classic EFI that will lose power like the battery has been disconnected while riding, then after a couple of minutes turn the switch back on everything comes on and starts. sometimes it will not idle until a few starts, then sometimes it will idle as it should. it happened a couple of years ago on one ride. Then hadn't done it again till this past Saturday it died 5 or 6 times. Then it died once this morning on the way into work. Not sure if it is connected but the bars got changed before the first time it did it. I checked the connections and couldn't get it to die while it was idling and I had washed it a week before last Saturday. Thanks!
If you mean the entire bike goes dead (lights, gauges - just like the battery is disconnected) then it comes back after turning it off and letting it sit sit, you have an overheating eyelet at the main circuit breaker. It gets so hot it will thermally trip the breaker.
If that is the exact symptom (total loss of power), if you turn on the bike, and you touch the breaker posts you feel one is extremely hot. You need to replace the bad eyelet(s). Harley did an update to a maxi fuse, but that doesn't repair the resistance at the eyelet.
If the lights/radio stay on, this is not the failure.

Could be main breaker, or could be its time to pull the ignition switch apart to clean out the corrosion and contacts that can cause problems.
Hence main breaker (25, 40 amp, 74600-94A in blow photor) on that year bike has the alternator first on the gold post, then rest of the wire on the silver post, so is main breaker trips from other heat, the battery will not charge until the breaker resets, but it should not kill power to the bike instead. Plus that fact that he is playing the ingnition flip game that seem to solve the problem, would still beleive that the problem is in the ignition. Hence had problems with my lights during rides, that turning bike off and back would solve, and proof was really show by the amount of corrision/burn on contact bars, when igntiion was cleaned to solve the problem in the end.
or it too far gone, and that ignition needs to be replaced

Just keep in mind what you will need ingestion switch tool to put it all back together in the end, ie get the lower section aligned, before you can push the upper lever back down in place and lock it home.

I didn't have an issue but replaced mine just based on age Harley says to replace main breaker 2001-2003.

I would also play with ignition switch. If cycling that bring the power back on could be that too.

Well got a new main breaker and it seem to have solved the issue. Rode to work yesterday about 30 min ride one way. Ran like it should no loss of power. Thank You for all the help! I appreciate it!
