I've had this happen multiple times when my stock alternator was eating brushes. Car ran almost 40 miles on battery power each time (go Optima!). Started with one idiot light and then the rest tumbled. Was able to drive for about 15 minutes once all the lights came on.
The OP's problem with the coolant gauge was resolved with a new alternator. I recall having similar twitches with the coolant gauge when my brushes were going out.
