1999 Ford F-250 SD: sudden loss of power

Filed Mar 27, 2014 · Fuel system · NC

We have started to notice that when driving at a steady speed the truck will stall and lose power as if it was out of gas. This has happen too many times and has become such a scare that we are completely paranoid to drive the truck without the fear of being rear ended. At take off the truck will sometimes jolt forward violently. We have noticed and recorded that these problems occur only when the truck gets to half a tank. The problem has gotten so bad that after a complete fill up the truck will now just cut off while being operated on the highway and have to be restarted. We have several ford vehicles both personal and for our fleet vehicles. The fuel filters are becoming completely clog up due to the poor condition of the fuel tanks themselves. We have spent countless hours researching these problems, and spent excessive amounts of money trying to fix/repair these problems. It saddens us that we have become just another added unsatisfied loyal customer to ford, whom has no thought of correcting this problem. We have read so many other complaints and there is still no help for us. It just left in our hands to try to find a solution to fix this faulty problem so we don't get out on the highways and kill someone and or ourselves while operating lousy ford trucks and vans! We think it is time for ford to give us some help!!!!!!!

Ford 1999 f250 5.4l triton v-8 blew spark plug. Lost power, created road hazard and scared the crap outta me when it blew. Made it to side of road safely and got towed. Went online to find out this is a huge problem with this engine as well as other tritons. Spark plug threads are very short length. Not just poorly engineered but engineered to fail. Have read posts saying fires were caused by this problem when fuel mixture ejected from hole caught fire from arcing blown plug. Others claim the plug blew a dent into hood. Cannot imagine the damage to an eye or other if mechanic or other person is looking down into engine looking for reason for ticking noise, when bam, the plug blows out. Ford will fight this tooth and nail because it is an expensive fix. They make tons of money by having their shops pull the engine and replace the head. Please help us.

I own a 1999 f-250 truck with a v-10. Recently returning from an out of town trip one of the spark plugs blew out of the cylinder head while driving on the highway. Immediately lost power and pulled onto the shoulder. Speed limit for this section was posted for 75 MPH. Limped the vehicle home for approximately 25 miles with a strong odor of gas, was worried of potential engine fire but needed to get home with my travel trailer and atv. Did not want to leave all this on the side of the road. After internet research seams that this is a common problem with the ford triton motor design. Poor engineering.

While driving ,the truck just shuts down losing all power steering and brakes. This happened while in left hand turn with a semi tractor trailer right beside me. There have been several occasions this has happened. My mechanic has replaced the cps (cam position sensor) twice in the last two months. It seems to fix it for a while but the problem resurfaces without warning. I have found online that many people are having the problem.

Engine died while traveling at approximately 60 MPH and going around a turn on a 2 lane highway. Since loss of power, also had loss of power brakes and steering. Had to slowly pull vehicle over shoulder of road. It restarted after several attempts. This happened about 4-5 times, before it finally would not start. Had it towed to dealer. It was the camshaft position sensor. Was told this is a common problem with this truck. I have also heard from many, many other owners to keep a spare in the truck as this will happen many times. This is a safety issue when traveling at highway speeds and loosing power and ability to control vehicle. Ford charges between $150 and $190 for this part, which the company knows is a problem, thereby making a large profit on their mistake.
