Takata recall. While driving on a city street, truck suddenly lost power and shut off in the middle of an intersection, while I was turning.I tried several times to start it but nothing. I believed it to be the catalytic converter, and had it towed to a muffler shop. After fixing the problem truck still would not crank. I had to have it towed once again to my residence. Before this I would have to make 2-3 attempts to crank the truck before it would start. Also prior to this I noticed I have not been getting as good of gas mileage as I should and the truck would not accelerate as it should. I have done research and seen a number of people with my same model truck have several issues with their fuel pump.

On multiple occasions the vehicle has lost power at highway speed and the engine dies. After a few attempts the engine restarts and operates normally for an unpredictable interval. This has happened at least 10 times. The authorized dealer and other mechanic shops have not been able to diagnose the reason for the power failure as they have not been able to cause it to duplicate failure when they have it. This sudden unexpected condition is very dangerous when it occurs and renders the vehicle unusable for anything other than short usage.

Reduced engine power. This has been occurring off and on for about 9 months, have taken it to dealer multiple times and replaced everything that was said would fix the problem. The problem still occurs even after replacing: accelerator and receiver on throttle body as well as checking wiring harness for issues. Essentially, the vehicle will lose the function of the accelerator without warning at any given time during the use of the vehicle. The dealer has told me that they don't have any idea why it still is having this issue...the other day the vehicle was being driven and reduced engine power mode set in and at the same time the power steering went out. Thought the power steering going out at the same time was a one time deal but it happened again the very next day. The vehicle had this issue on the highway the other day and nearly caused an accident. It is shocking that there are not thousands of complaints with this same issue, if you look up forums on this topic there are over 200,000 threads on this very issues. There are thousands of forum complaints about reduced engine power and how people have spent $1000 plus at the dealer and the issue still persists. The drive by wire functionality instead of using a throttle cable seems to be having issues that even gm doesn't have an answer for. Would appreciate any looking into on this subject.

My son was driving, we were returning from prescott az. We were on a small down hill part of the road when the truck lost all power. I told my son to put the truck in neutral and try to restart it. That failed, it made the same noise as a dead battery would. I told him to pull off the highway. He did so and put the transmit ion in park. I told my son to try and restart it and it started right up.

I own a 2003 chevrolet silverado and as I am driving down the road the check engine light comes on as says "reduced engine power" and I am only able to travel between 20 to 30 MPH and also as I come to a stop light/sign the truck wants to sputter out and die. Everytime I take it to a mechanic shop they tell me its the throttle body and that it needs to be changed but I have already changed it 4 times in the last two years and is not the problem. The problem is constantly happening sometime 3 to 4 times a day.
