2006 BMW X5 Fuelpropulsion System Problems

WHILE DRIVING ON INTERSTATE IN HIGH SPEED LANE ENGINE SUDDENLY LOST POWER CREATING DANGER OF REAR END COLLISION. IN MOVING TO BREAK DOWN LANE ENGINE CONTINUED TO RUN BUT WOULD NOT PROPEL THE VEHICLE OVER 5 MPH. THIS PROBLEM HAD OCCURRED TWO WEEKS PREVIOUSLY WHEN THE VEHICLE WAS TOWED TO BMW DEALER FOR SERVICE. AT THAT TIME THE VEHICLE WAS ELECTRONICALLY DIAGNOSED AND NO FAULTS WERE FOUND OR REPAIRS MADE.THE VEHICLE WAS AGAIN TOWED TO THE BMW DEALER AND NO ELECTRONIC FAULTS WERE FOUND. THIS TIME A MECHANICAL DIAGNOSIS WAS PERFORMED AND FUEL PRESSURE WAS FOUND TO BE 12 PSI RATHER THAT THE 55 PSI SPECIFIED.
