Welcome.
Electric fuel pumps can be a problem like anything else mechanical on the bike, but I don't think it's that common. What seems to be more common are pinholes in the fuel lines inside the tank. Usually from the line rubbing the tank wall. There's also a filter in the tank, you didn't say how many miles you have but it's something else to check.
Why do you ask?
I have like 48.000 mls . When I open my throttle fast de engine drop dead . Then I have to switch off my contact , back on and wait until the fuel pump stops pumping before the bike will restart
The first thing I'd do is fill the fuel tank all the way, take a ride and see if that fixes it. If it does, you have hole in the plastic line inside the tank. Fairly easy fix.
The second thing I'd look at was the fuel filter. WOT fuel starvation can be a sign of dirty/clogged filter that doesn't flow enough fuel. Easy fix with Youtube and some tools.
If those two things didn't work, I'd look at the pump. But start with the easy, basic and cheap stuff first.

I think I do that , thanks for the advice , the pump runs a few seconds
Is there something like a MAP , MAS sensor or an Intake air controle valve on this bike ? because maybe something like this could cause the problem also I believe
