thank you for the info. I will try those things and let post what the problem is. I did some research and found that I am not the only one having this problem, it may be something that is common in the 05's. I was also told that it could be the coil pack. that if the coil pack has a hair line crack in it, it will heat up, when it hits a certain temp, it has an automatic engine shut off? does this sound true?
