Indeed it sounds like that it could be related to resource utilization. What I could suggest before increasing your resources is:
Try using a caching plugin like WP Super cache for example. That will reduce the overall server load.
Remove any plugins and themes that you are not using.
Try using Redis to store your PHP sessions, that way PHP would spend less time writing sessions on disk.
Tweak your MySQL service for better performance and reliability:
