So your camera has a life expectancy called a shutter count, which is based on the sensors exposure to light.
The life expectancy of a shutter is based on actuations, not the exposure of the sensor to light. The shutter mechanism just plain wears out.

So... I'm sorry, I'm not too educated with cameras... But I have a Canon T2i, and it only films about 1-3 minutes of video. It used to film the standard 11 or so. Could this be the shutter lifespan that you guys are talking about? I had to buy a video recorder instead, but the obvious difference in quality pains me.
I would blame this on your battery before your card. Reading further down the thread, I see you're using a class 10 SD card. Provided that you're using at least a 32 GB, class 10 SD card, you're probably alright. Video is taxing on your camera's battery. Over time, rechargeable batteries discharge quicker and quicker. Try replacing your battery. Even the cheap aftermarket batteries made for your camera are of pretty decent quality. I have many, many, many of the aftermarket batteries and am quite pleased with them.
Ladies, as far as wear and tear on your dslr cameras shooting video. I wouldn't worry about it too much for shooting video under 30 minutes. I also wouldn't recommend (nor do I believe you'd have much success with) running your camera for the full length of a cam show.
All modern cameras have a thermal shut down that will turn off your camera if the sensor starts to get too hot. I can't guarantee that repeated shut downs due to high temperature
will damage your sensor... but frankly it's not worth the risk. I never shoot video on my main photography camera. Some of you may not have the funds for two or more cameras... but if you do, I certainly recommend having one dedicated to still photography and another dedicated to video.
One last bit of advice:
Magic Lantern! Get it. It's free. Use it!
I'm working off of the assumption that most of you are running Canon for video as it has been the most mentioned camera in the thread thus far. I don't believe they have rolled out a Magic Lantern firmware for Nikon just yet but I may be wrong... I shoot Canon and therefore have no reason to find out if they offer Nikon firmware.
Magic Lantern has settings to automatically restart recording after your 12 minute (or more accurately, 4gb) recording limit. There will be a half second or so of video where the sound drops out of the first clip but it's pretty easy to merge in post... certainly easier than pushing the record button again (assuming you've noticed that video has stopped recording).
You'll also be offered tools to expand your ISO and White Balance settings to achieve more accurate exposures and color. Magic Lantern actually adds a lot of capabilities to your camera... way too many to list. But the basics are probably more than enough to sell you on it in my opinion. I no longer shoot video without Magic Lantern.
At this point, you want to avoid formatting your card in camera since the Magic Lantern firmware is actually stored on your SD card. Just delete the videos manually after you've transferred them to your computer. I actually don't even delete them from the card via the computer to avoid accidentally deleting my Magic Lantern firmware. I put the card back in my camera and delete the videos via the play/delete buttons, deleting them individually.
I tend to ramble so... Hopefully there's some info in there you can use.
