Default '08 Grand Prix Sensor/computer issues

On Saturday my wife left with out daily driver '08 Grand Prix and returned 5 min. later saying that the info panel started beeping and giving warnings of "hot coolant" "A/C off to conserve power" "Traction control off" and other things. She came home immediately and told me about the problem.
I went out, started it and it started right up but the rpms surged a couple of times almost stalling once, then settled down to normal idle. I backed out of the drive and when I put it in drive it again beeped and the "hot coolant" message came on the info panel.
I pulled back into the garage, open the hood and checked the coolant recovery tank, couple of inches in bottom of tank. Top radiator hose was hot, figured it should be if coolant was circulating.
Took it back out for a test drive, it started right up, idled smoothly and there were no problems on the 5 mile trip I took.
My wife then took it to run her errands with no more issues.
I used it yesterday again with no issues.
Has anyone else had anything like this happen to them. I'd like to think it was some kind of one time only freaky thing but something inside my head tells me it will pop up again sometime and probably not so close to home..
