2007 JEEP COMMANDER 4X4 Fuelpropulsion System Problems

DRIVING STRAIGHT AHEAD AT APPROXIMATELY 70 MPH ON A TURNPIKE THE ENGINE AND ALL POWER IMMEDIATELY AND INSTANTLY SHUT OFF. VEHICLE HAS APPROXIMATELY 110,300 MILES ON THE ODOMETER. QUITE A SCARY CIRCUMSTANCE. AS I WAS PULLING OFF THE MAIN FREEWAY TO THE SHOULDER, I TURNED THE IGNITION TO START AND THE ENGINE IMMEDIATELY STARTED, SEEMED TO RUN FINE, AND I PROCEEDED ON AS IF NOTHING HAD HAPPENED. NO ERROR OR WARNING LIGHTS WERE ON THE DASH. 5.7L HEMI ENGINE. THIS COULD HAVE RESULTED IN A VERY BAD ACCIDENT.

VEHICLE WILL IDLE ROUGH AND STALL AFTER 15-45 SECONDS AFTER STARTING. WILL NOT STAY RUNNING IN P,N, OR D. *TR

THIS HAS HAPPENED TO ME SEVERAL TIMES IN THE TWO YEARS I'VE OWNED THIS VEHICLE. EVERY TIME I TAKE IT TO THE SHOP THE MECHANICS SAY THEY CANNOT REPLICATE THE ISSUE SO CANNOT FIX IT. FIRST THE CHECK ENGINE LIGHT WILL COME ON AND NO CODES WILL APPEAR WHEN RUN. A COUPLE DAYS LATER (MOSTLY WHEN DRIVING ON THE HIGHWAY, OR ANY SPEED ABOVE 30MPH) I WILL BE DRIVING AS USUAL AND BEGIN TO INCREASE SPEED ON THE ON RAMP FOR THE INTERSTATE AND THE ENGINE WILL TAP OUT AT 45MPH. I WILL PRESS THE GAS PEDAL TO THE FLOOR AND THE ENGINE WILL NOT REV AND THE RPM'S WILL NOT INCREASE. I TRIED TO PUT THE CAR IN NEUTRAL AND BACK INTO DRIVE AND NOTHING CHANGED WITH THE ENGINE. ALL THE WHILE I HAD MY ONE YEAR OLD CHILD IN THE CAR WITH ME. EVERY TIME I TRY TO...

IT IS CURRENTLY STALLING, WHILE SITTING AT STREET LIGHTS. ALSO, THE GEAR SHIFT MODEL INCLUDING STARTER AND WIRING. *TR

VEHICLE SHUTS OFF WHILE DRIVING. VARIOUS CONDITIONS. IDLING, CRUISING AT HIGHWAY SPEEDS, ACCELERATING, DECELERATING, ETC. MUST SHUT KEY OFF TO RESET ENGINE BEFORE THE VEHICLE WILL START AGAIN. THIS HAS HAPPENED AT LEAST 20 TIMES WITH NO CHECK ENGINE LIGHT ILLUMINATING. IT HAS BECOME A HUGE SAFETY ISSUE SINCE ALL POWER IS LOST AT ANY SPEED. *TR
