Was my husband wrong and I was right saying not the battery.
My 2006 Ford Focus (purchased October in 2006).has run very well for several years. About 2 years ago, it started dying when I would try to start it. Two footed it many times from work, to home, from home to work. Well, a couple of days ago, I was driving and everything went blank on dash; engine still was going. drove home, turned off car, started up right away. Next morning; wouldn't start, just clicked. Husband replaced battery. I told him after research that it wasn't the battery or alternator. Bet a dinner. Hopefully I am right. Will keep you posted
