My car lost power assist to steering and brakes, and stopped running.

What is your question?

I was entering a parking lot when the yellow car with lights icon lit up and then the oil and battery lights came on. The car stopped running and lost power to steering/brakes. Headlights/wipers kept running normally. Did not hear it stall. Car restarted fine. Battery 1 month old. Alternator tested good 1 month ago. Is this caused by an overdue tune-up?
