Started yesterday while riding - noticed I have "gaps" while accelerating... Stopped at a redlight and it just turned off. Couldn't turn it on for like a minute (similar as in the video) - suddenly it came on again. I can't reproduce it on video but you can clearly hear that the Bolt has troubles staying on in neutral. Gas is filled up. Anyone has an idea whats up with my beauty?

Could be so many things.  But I think I would start with the sparkplugs.  How many miles on them?  Perhaps change them to fine wire iridium.  If the issue only comes about when you jiggling the throttle, then it may be that jiggling coupled with a weak spark.

If that doesn't cure the issue, then next I'd want to know if you are getting any error codes, and I'd want to know all the modifications you have done to the bike.  Or if not you, then the prior owners. It may be that your best bet would be to take it to a dealer and let them run some diagnostics on it.

Idling at Stop Light and your BOLT just turns off
(1) did you accidentally KICK Down on the KICK STAND ? (or is it loose, etc -
SAFETY Feature is when kick stand is lowered the BOLT turns off IF you are in GEAR....so you can Not RIDE off with Kick Stand down)

(2) you are having Opposite of my BOLT - 40 % of the Time , especially after riding 10 miles at 85 - 95 mph ....i pull into work Parking Lot
Idle RPMS is at 1400 .... or rare even at 2100 ....... Not all the time - we should idle around 800 rpm (i have a tachometer KOSO unit)

Make a video with you just turning the key. The fuel pump sounds kinda off in the video.
If you have enough grease & a big enough hammer, you can put anything... anywhere.

Thanks E and chevy_1k9.

I've uploaded 2 new videos - one shows the key turning, the other is another one where you can see that the bike is almost turning off.

To me it sounds like the fuel pump. I put some videos of what other peoples pumps sound like. These videos sound like my pump.

chevy - the FIRST or TOP video i listened to - is how my BOLT sounds
krambam - your 2nd or BOTTOM video has your BOLT making a louder, different sound - bummer , i am guessing chevy is right in that your FUEL PUMP needs repair or replaced
