My car is doing the exact same thing, it also stops running while I am driving it so be aware....I was on another site and these 2 problems seem to go hand in hand. I have had my car in the shop 3 times in 3 weeks, they cannot find anything b/c it is not throwing a fault code. I am in Ohio so if you ever find out whats wrong with yours give me a shout back! I am waiting to see if a co-pilot can be attached to my car which is supposed to record the problem when it happens. Good luck...I have only had my car for 4 weeks . IT looks good tho!
