Other safety measures than fuel cut due to boost?

Does the stock engine management have other safety measures than fuel cut at high boost?

As written earlier I have what seems like a fuel cut at high boost, but measuring at my FCD, it reads a constant high of 4,017 volts, which is below if the 4,3 volts I know of results in fuel cut.

 

Now, can it be a bad fuel pump? Does the engine management have a safety measure of a low AFR or something and cut of fuel? Or anything like that?
