Engine Shut Off Without Warning problems of the 2005 Ford F-150

I was driving in my 2005 Ford F-150 5. 4 when the engine shut off on its own. It was not the first time. It has happened while I'm driving in the middle of traffic. Just recently I was driving when I started to loose power, but this time started hear a loud banging coming from the engine. I drove the truck with almost no power to the mechanic. There I was told that it a cam shaft issue. As they uncovered the engine ii was told I would a new engine at the cost of $7500. As I later went online I found many people complaining about the same thing with Ford 5. 4 engines. It seems to me Ford knows about the problem but are not willing to stand by their problem. I have kept up with the maintanance since have been the only owner of the truck. I love the truck but I'm very disappointed with Ford not taking responsibility for having engineered a bad engine. I the single provider of my family and don't have money to be throwing away on new vechical. I also believe the truck stalling out in the middle of a highway was completely dangerous and I was lucky not be hit by anyone else. Please help.

2005 f150 goes into "fail safe mode" and shuts down while driving. It only occurred once per year starting at 65,000 miles, but now happens every 3-4 weeks at 114,000 miles. Once the engine shuts down, I put the transmission into neutral while coasting and it restarts easily. The engine light illuminates for 3-4 days and then turns off. In researching the issue, it seems to be a rather common problem with this vehicle and is usually caused by a faulty throttle body. Ford states that they are aware of the problem.
