Having decided, as I was still up, to drive to an all night store at approximately 02.00hrs, just to get some milk, my Jeep decided, after about one and a half miles, to go on strike! The engine just stopped; no warning lights, no reason. I had to wait over an hour for the R.A.C. (A U.K. breakdown/rescue service) to arrive, having drained the battery trying to get the 4 litre engine to fire. As I was stuck on one of the darkest roads in the County, I couldn't see sweet fanny adams under the hood, but jiggled all the ignition leads, knowing it had to be an ignition problem. Sure enough, Mr. R.A.C. man confirmed a small fault at the coil end of the ignition chain, and got me going again. Eventually got the milk, and arrived home at approx 04.00hrs, ever so slightly p****d off!
