Kinda sounds like you are having problems with your VATS
system but I wouldnt think you would with that low of miles.
Then again Im not sure if that would cause the car to cut off
while driving or not, I know it would keep it form starting.
You need to pull your codes, the way you do that is to hold
down the options button and press the fuel button 4 times while
continuing to hold down options. It will then cycle through and
read out all the codes automatically. It cycles at a rate which is
typically too fast to copy them down so you will want to go
through them manually once it finishes. The first four buttons
on the dash will allow you to scroll through, I cant remember if
its the first two or the second two that allow you to scroll
through the subsets but you should be able to figure it out from
there. Once you get all the codes post them up on here with
the corresponding H or C that follows it.
