Our 2021 850 did this as well. It was most noticeable if it was cold, and the machine would flutter in and out for 30s - 1minute (occasionally dying altogether). We took it into the dealer for the first service and asked about it. The answer from them was to stop putting 91 octane fuel in. I was surprised, but switched to 87 (which is what our manual recommends) after using up what was left in the tank, and then have had zero trouble with it since.

I'd be curious to know what octane fuel people are using who are having trouble and what altitude they're at (we're at 7,500ft, which means the standard grades of gasoline are lower octane than elsewhere).
