Just been out for an hour drive in her, and all is well. When I got back, I turned her on and off a few times and no problems. Meter read 12v from when key was put in to just as engine turned and it went to 14v.
Maybe it had to do with the recent short 6 mile round trips I've been doing to the train station. But then again, it suddenly hit me that maybe I was just being a muppet and didn't have my foot on the clutch. I dunno. Too tired then and really way too tired now.
Thanx for the helps peeps. If she does play up again (and I know that I have for certain put my foot on the clutch pedal), then I'll just post back in this thread.
