ECOBOOST ENGINE: 7/06/13 FIRST TIME AFTER DRIVING 90 MILES ON I-10, PULLED OFF IN REST AREA. WHEN GETTING BACK ON THE INTERSTATE, WENT TO ACCELERATE TO MATCH TRAFFIC AND ENGINE FELL ON IT'S NOSE, FELT LIKE A STALL THEN BUCKED, MISFIRED , LOST ALL POWER. WHEN LIFTING OFF ACCELERATOR ENGINE RETURNED TO NORMAL. ATTEMPTING TO ACCELERATE AGAIN, ENGINE LOST POWER AGAIN. IT FELT LIKE EITHER BAD GAS OR IGNITION FAILURE. WAS ABLE TO GET TRUCK UP TO SPEED USING CRUISE CONTROL. WITH A LIGHT ACCELERATOR TOUCH, WAS ABLE TO MAKE IN HOME FROM PENSACOLA TO WINTER HAVEN, FL. FILLED UP WITH DIFFERENT FUEL AND PROBLEM SEEMED TO GO AWAY, SO I DID NOT TAKE IT TO DEALER. SECOND OCCURRENCE 11/16/13 WHILE HEADING TO PENSACOLA AFTER DRIVING SEVERAL HOURS (70-75MPH), WHEN PASSING A SEMI GOING UPHILL ON I-10, FASTER TRAFFIC WAS APPROACHING FROM BEHIND, SO I ATTEMPTED TO ACCELERATE TO GET AROUND THE SEMI TO CLEAR THE LEFT LANE . ENGINE FELL ON IT'S NOSE ONCE AGAIN, STALLED, MISFIRED, SHOOK AND LOST POWER. THE TRAFFIC WAS UPON US IN SECONDS. I WAS ABLE TO GET TRUCK BACK UP TO SPEED BY GENTLY USING CRUISE. THIS TIME TOOK TRUCK BACK TO DEALER. THEY INSTALLED A "SHIELD OR PARTITION" IN THE CHARGE-AIR AND DID A REPROGRAM. CURRENT MILEAGE IS 14,800. DEALER DID NOT SEEM CONFIDENT THAT THIS WAS THE FIX. WE WILL SEE. *TR
