Stopped by the dealer today and talked with the service writer, and then one of the techs... Definitely sounds like a switch or electrical problem. The tech mentioned a switch on the motor as a possible problem.
I got home and got to thinking... I put the top down and up a few times today before I left to go do errands, and it worked fine. Then when I stopped at a store, the top would not go up... had to mess with it for a few minutes, then finally it decided to go up.
After being home for a while, I decided to put it in service mode to check the motor and see if I could find this switch the tech mentioned. Well, the top didn't want to go down at first.
So I started thinking... Maybe it's heat soak in the motor. It's getting too hot, and won't run. I know that starter motors on old 911s can get temperamental when they get hot, often to the point that they won't respond to the ignition switch at all.
What do you guys think? Since the switches seem to work OK, maybe it's a bum motor?
Has anyone replaced the motor themselves?

Hi,
I don't think it's a Heat Soak issue at all. The Top Motor runs in 20 sec. intervals and then not again for sometimes hours or days.
There are a number of micro-switches in the 'B' Pillars and such which are much more likely to be the culprits, even corroded connectors is more likely than a tempermental motor. These micro-switches are, by their very nature, not the most robust components in the car. It the Motor is faulty, it is most likely so simply quit working than to operate intermittently. Good Luck!...
Happy Motoring!... Jim'99
