My engine is stalling why?

I was driving on the highway when my car suddenly shut off. When I tried to restart it, I only heard clicking and no dash lights came on. When I pressed the brake pedal after about 20 tries, the lights came on & the car finally started. Ive been trying to research the issue myself but there are so many possibilities. Can you please suggest what the problem may be? I read about the radiator temp fan thing but it wasnt really hot outside & I hadnt been driving the car for very long.
Thank you!

Thank you so much. I will let you know the outcome :)

I have a 96 toyota corolla that has got a skip to it. I replaced the plugs and throddle positition sensor. The car runs fine when you first start it and when it warms up it starts skippin. As you are driving the car jumps at first and then levels out thru all the gears. Also at 55 the car runs fine and then skips and fine then skips. When ever you stop at a stop sign the car dies. I dont know what the problem can be please help.

It will crank but won't stay running.

It turning over but won't stay grinning at all. It's like it's not getting power.

What checks?
