I don't know of any way to do that, because until you know the circumstances of how the blank page occurred, you can't really do anything about it.
The only thing I can think of is a little JavaScript right in the header that sets a variable to 1, and then add a userLoadScript() function that sets it to 0...then have a timer-driven function that checks the value and if it is still 1, reload the page???? Then you are never guaranteed that the header JavaScript will even show-up!
You just have to start acquiring as much information as you can on the circumstances of the blank pages; when and how, doing what and so on...then narrow-in on where in your scripts there could be a blank page resulting...
