Keeping shutting down and take a long time to boot up

Hello,

My 13” MacBook Pro Mid 2014 is starting to act strangely.

My system suddenly turns off, and when I try to restart it I don’t get a response. It took a few days or maybe 12 hrs until I could turn it on. But, when it turn off properly it acts this way again.

I’ve done Power+Shift+Ctrl+Option All it did was just change the color on MagSafe, and when I press the power button, it still will not boot up. Trying to P+R+Command+Option keys, is still the same.

Can you help me fix it?

What’s wrong with my system?

Suddenly my macbook turn on.

here’s the picture..
