Instead of asking us for help, with it being new its probably better to contact customer support.
If a macbook pro / or regular mac shuts down, there are a few common things that can cause this:
1) hard disk - if that's the case, you'll need a new one OR you'll need to replace the whole computer
2) other driver / motherboard issue - I had a fried circuit that sounded awefully similar, and yep, had to get a whole new computer.
3) software update - you should always try this, first, before anything else.
If it's not the software or a bad battery though (does it stay on when plugged in?) then you'll need to take it to a specialist to see if it's a hardware issue that needs fixing.Does Ares run on a mac?
