 * On some days, the use of the site CPU resources reaches 100% and the site is 
   Down and after a few hours this problem is solved automatically. I disabled all
   plugins but this did not reduce CPU usage.

 * Try analyzing access.logs to find overload reason.
 * Maybe you have brute-force attack on your wp-login.php
    Maybe some bots (legal
   ones and bad ones) are trying to agressively crawl your site.
 * Solution will depend on findings.

 * You should monitor and find out which process utilizes the most of your CPU. 
   Depending on that you should install and configure Fail2ban for WordPress for
   wp-login.php and xmlrpc.php or activate caching (one of WordPress caching plugins,
   redis and memcached).
