Piddler, I would start with your electrical system condition. If these cars are not getting enough volts/power they will go crazy. This is just a starting point, you could have a bad fuel pump, broken balancer, burnt wiring harness and a 100 other possibilities.

My first guess would be an electrical problem. If a connection heats up the metal expands and creates an open. Did you let the engine cool down after it first gave you trouble or did it fire up right away after the engine quit? The motor needs, gas, spark and air to run. Checking for proper fuel pressure is also a good idea. As far as air goes you want to look for excess leaks into the system. That's more likely to cause stalling issues when you release the throttle.

If this wasn't a computer controlled vehicle with multiple coil packs, I'd guess it was the coil, but your best bet is to have the battery thoroughly load tested and, if necessary, replace it. These cars don't seem to like weak batteries.

21K on an '05 suggests it doesn't get driven much. How old is the battery?

If the dash is going black, it's definitely an electrical problem, I would start with the battery and check the cables. I don't think anything mechanical (ie fuel pump) would cause the dash to go black.

I've seen a bad battery do exactly this. Usually, however, it gets worse pretty quickly. Within a few days it should be intermittently failing to start at all. The problem is so common that you need to confirm the battery and battery cables before moving on to other things.
