Sorry, I should have made my answer more elaborate than the one-liner.  As 
Joe Elliott pointed out, I did not specify under what conditions does the 
system shut down the fuel pump.  In earlier GTV6's there was an intertia 
switch that when activated (usually when the car is upside down), would 
shut down the fuel pump and in all L-jet systems, the fuel pump would only 
run when the microswitch in the AFM was off (the flap, when fully closed, 
closed the switch).

Your pump should run continuously, however, as long as the engine is 
running as long as you haven't gone belly up or the airflow stops flowing.

The pump should also stop running if you blow the fuse, or the fuel pump 
relay (the one against the firewall) stop working ($90 from your Alfa 
parts supplier).
