There is and insertia swicth in your trunk that can cause losse of power to fuel pump,but this is usually caused by someone bumping your car.

Ok,i done a little research,your car doe,s not have a inestia switch,it is biult only with a low oil sending unit cutoff,if car is low of oil it will not let pump cut on,or could be bad sending unit,the only other thing that will cause this is your anti theft system in your car.
