Car won't turn over?

This morning at had to be at clinicals about 10 minutes ago. I went outside to turn on the car, and as I turn the ignition key, I hear a click and all the power goes out without the engine turning over I tried in gear and in neutral. So I'm sitting thinking what it could me, then I open the door(interior lights are not on), pop open the hood, then my lights come on. I could turn my headlights on and so I proceded to turn the ignition key and "click", engine doesn't turn over and the power goes out.

The power eventually comes back on within 30 seconds, but immediately turns off once I turn the ignition key. Could it be my starter motor pinion stuck in the flywheel?

Lately things all of a sudden have been screwing up on the car(transmission cooler line came lose, rear drum cyclinders leaking and left drum spring missing, transmission problems,etc.... Now I really believe the Fix Or Repair Daily saying

sorry guys it took a while to post. I feel back asleep. I'm going to wait til the sun is out so I can have some light. I do have a stock starter. I keep yall posted.

Ok...find out everytime I was tapping on the battery cables, power would come on. Appears that the positive cable is loose. I just don't have any sockets at the moment to tighten it. It did start up! Just don't know if I should risk taking it somewhere where I can borrow some sockets, so I'm just going to wait on a friend.
