What cuts off? Do you mean turns off? Please read Writing an effective Apple Support Communities question.

That is a warning that the drive is failing. This may only be a formatting problem or actual hardware failure. Follow the instruction to back up your files quickly. Once you have done that then I would proceed to an Erase and Install:
Install El Capitan or Later from Scratch
If possible backup your files.
This will install the version of OS X you had installed.
If this fails then you will need to replace the drive.
Thank you so much for your response. I followed steps 1-5 without any changes.
Then I did step 6, and held down the COMMAND and R keys as instructed. The computer finally booted. This is the final screen that I’m left with:
Red Octogon sign with an Exclamation Mark inside ‼
The message: Running First Aid___________
First Aid process has failed. If possible back up the data in this volume. Click Done to continue.
I wasn’t able to perform the Erase. The disk failed. I will need to replace the hard drive. At least I have a backup on an external drive and I had used Time Machine regularly. Thanks so much for your help.
