my vovlo shut off on me twice and almost a third time, one while at park, and one on the highway. but after i waiting i min it turned on. its also making a clicking niose around the fuel injecter, it very strong right around the fuel pressure regulator. is that normal. what should i check for and how do i check them for the shutting off?????

 

Did the check engine light come on at all?
Could possibly be a bad mass flow sensor.
Could possibly be a bad Throttle position sensor.
Could possibly be a bad engine speed sensor.
