Vehicle Shudder problems of the 2009 Ford Focus

After driving only a couple miles from my place of departure, speed 45 mph, my car suddenly began to decelerate (and the check engine light, the "wrench" light, came on. When I pressed the accelerator nothing happened, my car continued to decelerate. I pulled over to the far right lane (no shoulder), braked and the car jerked to a stop; I put my hazard lights on. I tried putting the car in neutral and then back in drive, but the car still would not accelerate. I turned the car off. When I restarted, the wrench light was no longer on and the car ran normally. This happened again on the same road, at about the same place (a couple miles from work) a month later on January 18, 2012. Then it happened a 3rd time February 13, 2012 about 3 miles from home. Each time it happened the same way--after driving only a few miles (5-10 minutes running time) there is sudden, uncontrollable deceleration (when I am trying to accelerate between 40-50 mph), wrench light comes on, no response to pushing the gas pedal, I pull out of traffic just in time while continuing to decelerate (had about 30 seconds to make this happen), brake to complete the stop, the car shudders to a halt, I shut the car off, restart and the car acts perfectly normal again.

While driving my 2009 Ford Focus on a trip the car lost power and coasted to a stop. The engine began to violently shake the car. The wrench light came on. We shut the car off and restarted it. It worked fine. On the return trip home the car did the same thing. We took it to the dealer, phil long Ford in colorado springs, CO. They said nothing was wrong with the car. It's still under warranty and they refuse to repair the car or look further as they told me they are losing money to do so. The mechanic doesn't get paid nor the dealership, it's a lose-lose for us - "they aren't part of Ford" was also in their response. Sorry, but you're out of luck. I've sent a letter to the president of phil long and Ford motor CO. I was told a service manager would call and help after this. 10 days have passed and nothing has happened. The car issue is dangerous as it almost caused an accident. Further non work on this may cause loss of life or an accident yet. I believe Ford and the dealership should take this seriously. The car again is under warranty and no one is willing to assist because their computers don't register an issue.

I was driving on the freeway at approximately 65mph, when the car lost power. Stepping on the gas pedal had no response. I put the car in neutral and coasted out of traffic and onto the shoulder. When I stopped on the side of the road, the car was shaking violently as if it was getting ready to stall. I tried repeatedly to step on the gas but there was no response. I turned the car off for approximately 30 seconds and tried to restart it. It started right up and the throttle was acting normally. Since that first incident, over a year ago, this has happened six more times with the last one being on 11/14/11. I was travelling at 70 mph on interstate 15 going north up the hill from baker, CA when this happened. Trying to Dodge the other motorists and the big rigs to even get to the shoulder was very scary. I have researched this problem and apparently it is not unique to my vehicle. Someone is going to get seriously injured if this issue is not resolved. As other complaints have stated there is no code left on the computer after I restart the car so my mechanic wants to drive my vehicle until it happens, but it only happens every couple of months. I can't be without my car for that lenghth of time so I am very frustrated.
