Really need some help today!

I'm out of town and my wife has the Box today. She just called and says she can't get it to start. Naturally this kind of thing only happens when I'm not around and generally "fixes" itself when I show up. Given that it ran just fine last night - and hasn't previously shown this type of issue - I could really use some advice. Unfortunately, I don't have much info (she had to take a cab to work so I couldn't quiz her much) so I'm kinda looking for info on what SHE might be doing wrong. I'm starting on the premise that I didn't leave the lights on last night and kill the battery. She got into the car using the remote. She's only driven it a couple of times - so.... What do you think! I need some possible solutions within the next 6-8 hours (it's 1:13 here in Chicago) to trouble-shoot by phone when she gets off work.

It's a '99 with a manual. Less than 15K miles. Mild weather today. Driven every single day.

Thanks!
