I have a MacBook Pro 13 inch early 2015 model. For the last few days, my MacBook started to sleep when I change the inclination angle of the lid. On repeated pressing of the Shutdown button, it wakes up.
Has anyone else experienced this? Does anyone know the root cause?

Lastly, it can be hardware that is beginning to fail or failing.
A good way to check is by running Apple Diagnostics located on your computer. There is a process in which it should be run and you can read the full documentation at Apple's website.
