Hello
Today and two days ago i had problems with power loss during ride. The screen went blank for a few seconds, and there were no power available until the bike had restarted.
I have experienced this earlier, but only right after keying the bike on, so i have thought this might be an issue with the ignition. However earlier this has never happened at any significant speed- today it happened at 100 km/h, and the last two times have been after riding quite some time. Today i had even removed all keys from the keychain, to avoid anything pulling the key being an issue.

Thus i have tried to pull the logs from the bike, and these are the last two times i believe i experienced power loss:

To me it seems like two different causes?
Does this indicate that it is 1: Kickstand error and 2: Key problem?

If not- is there anything else i can learn from this?

I have attached the original log,  in case it may shed more light onto this (The parsed log is too big for forum storage).

I'll appreciate any thoughts or suggestions on what i should do. These power cuts are are not confidence inspiring, so i hope there is something i can do..

I'd send the logs to Zero, and then I'd take it to the dealer. Power loss at speed is nothing to be trifled with.

I had a similar power loss today on my 2017 SR while merging at 70 mph, had to pull off and restart the bike but no issues with the display.  Logs don't seem to show anything other than the drop in RPM when I pulled off to the shoulder.  I'll contact my Zero dealership tomorrow.
