2023 r1250rs intermittent fail to start?

[Jcrouch]

I ride pretty regularly but once in a while, when engaging the start switch, will bike will chug and fail to start. I used to put it in neutral and it turns over robustly and starts right away. Yesterday, however, I was had no luck, thought I was stranded. Waited a minute and it started robustly. I checked all terminals. All nice and tight. Battery is one and a half years old, as is my bike. I’m going to put it on the battery tender, but has anyone experienced something like this? When it does start it’s not like a bad battery. Any thoughts?
