Bike shut off after 2 minutes while idling in the garage

[Eames5]

Hey Everyone!
Yesterday, while I was getting ready to set off, my bike shut off while idling in the garage.
I tried to replicate it tonight, but i couldn't. I currently have about 1,300 miles on the bike.
Has this happened to anyone?

Another thing, my left heated grip is loose. I did contact the dealer who installed it for me. I noticed it a couple of weeks ago. The grip spins around.
Does anyone have a fix? Or I probably should just let the dealer correct their work.

Thanks!
E

Because of the loose grip, I assume that the screw underneath the rubber simply needs to be tightened.
