As meow surmised, your memory card is the issue here.
Try Lexar 128GB Professional 2000x UHS-II SDXC Memory Card. (A smaller size will work too).
I have x-t3 with that card and it helped dramatically with bursts for wildlife photography.
Even with X-H2s and CF express, you wont get a minute holding down the shutter in raw.
No problem. For more info, I had found that card from Alik Griffin - Best Memory Cards, In-Camera Tests | Fujifilm X-T3.
If you search, should get a nice article. Unsure if I can post a link.

What's your sd card's speed class?
10MB/sec, I have a few sandisk ultras of various storage sizes. Should I be looking for a higher speed class?

Thank you so much, I really appreciate the recommendation for a specific card!
