1990 honda civic stalling problems and clicking noise.?

[RainingAppleJuice]

Hi. I recently bought a 1990 honda civic lx that is having problems. I just got the car about a month ago and recently when I try to start up the car, it makes this clicking/buzzing noise and wont start. So I charged the battery and it seems ok for now. But the other day I started the car and started to drive. About 15 minuted later, I came to a stop sign and stopped. All of a sudden, the car just stopped running. The brake pedal wouldn't push in, the steering wheel wouldn't turn, and the key wouldn't turn either. But all of the lights were still on, including the instrument panel lights. I took the key out, pushed it into the shift release, put it into park, and tried to start it. It was reluctant but after a few seconds of chugging the car started again. I don't know what made the car stall, but it scared me, and it hasn't happened at all since I purchased the car. What could have made it stall? Thank you.
