Probably either a bad fuel pump , bad pressure regulator or a dirty fuel filter. Id start with replacing the fuel filter. Then get a pressure reading on the fuel line and also on the fuel rail if these fluctuate as you rev the car then its a bad regulator if the pressure is low then its a bad pump. Hope this helps
