Stalling 2006 ford f-250 6.0 diesel, I was driving on the freeway with my 2 boys doing problay 60 MPH in a 65mph zone when I noticed that the truck started first seemed to loose power then spurted, then 20seconds later the rpms dropped finding my self without no control of the truck what so ever, meaning it had no power brakes no steering and the engine completly shut off ! , coasting to the side of the freeway barely making it without getting rear ended ! I couldnt believe this. I got to the side of the freeway and tried for a good 5 to 7 minutes before calling triple a for a tow, then while waiting for them to arrive I tried it once again to start the truck and give it gas while doing so it fired up but for about 15 seconds it sounded like it was firing on 4 cylinders or misfiring then it went back to normal and made it home. I then took the vehile to the local ford dealership, I don't know as of yet whats wrong with it but I can tell you I was scared over this happening!

Spark plug numbers 2 and 7 blew out of the cylinder head. Number 2 blew out while driving down the highway and number 7 blew out starting off at a green light on a main street. There was a strong odor of gas when this occurred and serious vibration from the engine misfiring. This created a potential explosion hazard since the air/fuel mixture is designed to ignite from an ignition source. This jeopardized my safety as well as the safety of others around my vehicle. This is a known problem to ford and needs to be addressed for all vehicles manufactured that are affected by this problem. Mileage has nothing to do with this as owners of these specific vehicles with aluminum heads have had this issue at less than 100,000 miles.
