I bought my 8 last July and it had 60k miles on it, I've taken good care of my car since I got it and the engine has never flooded and for a while it drove like a dream. On XMAS day, I was driving down the freeway to see my family, but when my car came to a complete stop it died and had to be towed. The same incident just happened last weekend driving a shorter distance but down the freeway nonetheless, and at this time I just got my 65k maintenance with new plugs, filters and everything.

I replaced the battery which was dead but now I'm worried about even driving my car on the freeway now, it's a shame because I love this car and I have done nothing but take care of it. Any advice or tips?

 

so you had your plugs and coils changed? What about the wires?
was the MAF sensor cleaned when they replaced the filter?
Have you checked your CAT?
Also, you may want to check your fuel pump/ lines
