Looks like you unsuspended yourself already.
It seems like you're running WordPress and from the source code, you are using WP Super Cache, which is probably what's causing high resource usage.
When generating and saving the static HTML files, it uses a lot of CPU, enough to trigger suspension on free hosting. Even though it makes your site faster, the time it takes to make the HTML files uses high CPU power. Try disabling WP Super Cache. Caching plugins don't go well with free hosting.
I use Drupal and enabled the page caching, maybe this causing my suspension today (3 times). I wonder what I'll get if I suspended for 4 times.
Same as the third actually - 3 and up just require staff to unsuspend because if needbe, they can dig up the logs and find what's causing it.
