635d shuts down at full throttle

Hi, I have a rather annoying problem with my 635d. The engine simply shuts down under load:/ The first time reading out all injectors were in the FS. You will find the FS report enclosed. I then deleted the FS and drove slowly further. On a slight slope it went out again:€ In the FS only the 6 injector error code 004460 Controlling Do you think it’s just the one injector or something rougher?
