Car dying all the time lately, Battery seems fine though Options

[Timmyface]

Hey guys,
Over the last few weeks my cars been acting strange.

The car can start perfectly fine, and run for however long...but a few times when I've stopped the car, than turned it back on it wont start.
Won't turn over, no power going to it at all.

Yesterday, whilst Driving, my car lost complete power, including power steering (which wasn't too fun).
When i tried turning it back on, my lights on my dash came on for 1 second than dimmed back out. I touched a few things under the bonnet, than a minute of just sitting, it started.

Again today, done a small 5 minute drive, all fine. Come back to the car and it wont start.

Sometimes if i pop the bonnet it has a better chance, but most of the time if i leave it for a minute or 2, it will start.

I've looked for any loose/bare wires that i can see. Taped up some connections as a precaution... i don't know what else. Confirm its IN the engine area?

Any help would be appreciated, i don't want it to lose power in the middle of the highway

Thanks

Yeah i think this may have been the problem. I gave the battery a good clean all over, wire terminals etc, and bolted it all back on nice and tight. So far no troubles, so hopefully thats all it was
