just stops????

G'day Team,
I have a new problem. For some reason I will be driving along no worries when all of a sudden the car will simply die so I quickly slip it into neutral and turn the key & it starts again no problems, and then it might be a week or an hour before it does the same again?. I have noticed that when this happens the engine light will come on and the car will run rough, if I turn it on and off the light goes out and it comes good again?, "Any Ideas???" I have been told everything from leads to the coil to the fuel pump but nothing seems to work...

The first step would be to do an error code check. There is a how to, and the codes are listed in the articles accessed from a link on the main page.

My initial guess is the CAS, but it could be a number of things.
