Seems you car sort of recovers at 5500 and fuel returns. Overall, appears you are still down on power but why would it start delivering fuel again at 5500?
I am stumped.
Check connections (condition of) at the fuel pump relay? Swap another in there?
Do a test on volume flow. I don't know how many liters a minute the pump should deliver but make sure it is at least to spec.
Going out on limb, what is overall ignition advance? I don't know what happens to AF ratio if you get close to detonation. Just talking here, not professin'.
