It could be. But in most cases a regulator fails and leaks pressure and system pressure will drop.

I would look into leak injectors or faulty sensors. But it never hurts to test the fuel pressure.

Actually, many regulators have the diaphragm rupture and leak fuel into the vacuum system... I've had that one happen before. Just pull the vacuum line from the FPR and see if there's fuel coming out..
