Battery keeps going flat

[chris_p]

The car will be fine, I'll go for a drive, everythings good, pull up somewhere, try to start it 10 mins later and the batt has died. What could it be? Alternator? Help

Check voltage accross the battery terminals when its running. It should be between 13.6 and 14.3.
