Hello
I see you've checked for fault codes. Was that with a generic reader or Vida?
One item that can cause misfire on a stationary and moving car but no codes is the crank position sensor(CPS). Heat from a warming engine often the element that highlights a failing CPS.
Items that can cause a misfire on a car in motion can be ABS sensors and/or the ABS reluctor rings but you should see fault codes relating to this.
I have a Smart Roadster which had misfire and cut out within 5 minutes driving and would not start after. No codes were logged. I pin pointed it to the CPS by rapidly cooling it down and normal service resumed. A new CPS cured it.
Now I'm not an advocate of throwing parts at cars to cure symptoms but usually a non genuine CPS at your local factors is cheap as chips and at least you could eliminate that component then if not successful see if someone on here has Vida local to you and can run a diagnostic check, keeping inline with local Covid restrictions of course
