Vehicle once when first bought shut down during rain conditions when trying to excel. It was like you ran into a wall. Ford then said it was a wiring harness problem. It continued missing at times over the last two years. The same thing happened again in December while trying to pass a vehicle and it was again during rain conditions and just shut down in the road. We took it into the dealership and they said it was TSB 13 8 1 and made repairs. Vehicle now does not run right and gas mileage has dropped by at lest 2. 5 mpg. Noticeable power loss. Vehicle is the Ford 3. 5 echo boost. This is a big problem for consumers who want a truck and expect power with good mpg but should not be afraid to drive or get a supposed fix that's not what you have purchased. These situations will result into some very bad accidents. I cant imagine pulling something and this happens. Bottom line consumers deserve safe reliable vehicles. We love Fords and I hate I am having to complain but this is a real big problem. Please investigate. Thanks!!!!.
Engine stall-shuts down when it goes into passing gear. When you attempt to pass or enter onto a highway you accelerate and the engine shuts down.
