But what brings it on? Can you prepare for it to occur on race day?
It is not likely but always possible.
This posting from Fred Gratzon at The Lazy Way provide this insight:
Top performances flow without any mental interference whatsoever.
We have all experienced that even though we may have mastered all the physical aspects of a sport, we lose the ability to perform them well under pressure. Therefore, it seems to me that teaching how to think (and more importantly how to not think) will bring success more quickly than teaching how to replicate the stroke of a great athlete.

course, the space between your ears." Bobby Jones
The hard part is what to think about.
Thinking about nothing is actually the best.
