I am experiencing an inconsistent time out problem when opening options to a plugin, any plugins. Below is an example for when it worked.

There are times when that simple configuration won't load and exceeded the time out threshold in my PHP configuration (120 seconds). I also tried opening the options for other plugins and the same thing happened. However, as I mentioned above, the error is inconsistent. There are times when it would always time out, but there are times when the options load perfectly.
In cases of time out, I tried logging out and logging in again but that didn't do anything to solve the problem. I also tried restarting my Apache, but that also didn't solve the problem. Sometimes I just leave it for a few hours or come back the next day and the time out problem was gone just like that.
Any hints on the source of the problem?
EDIT 1
Below is the error message I got when it's not working. I forgot to upload it before. Sorry about that.

Number of plugins installed: 13
Number of plugins enabled: 5
