Another way to get around timing out is to write your post in notepad or Word. Check to make sure you are still logged into PC and then copy and paste the post and click submit.

I'm so sorry you lost the post. It's so frustrating when that happens. If you are using Google Chrome or Firefox for your internet browser, if you find you have timed out anywhere (not just PC), you should be able to hit the back button and retrieve your post.
