B400 - engine stalled after sudden braking

[Bela]

Yesterday, at 34°C (93°F) air temperature, I had a problem with my B400: the engine stalled after sudden braking. Afterward, I was able to start the vehicle by pulling the lever on the fuel pump. I wouldn't have expected this, since the fuel is still being flushed from the front. However, there's a short segment after the fuel pump toward the tank.

I've had the vehicle since 2019 and have never experienced this behavior. Is this a known issue?
