When it does this, come in to the pits and stop. Just let it idle and see what happens.
If the idle stays high and then stalls and is difficult or impossible to restart until it cools off a bit, it's probably vapor locking. Temps are too high, richen it up.
If it stays high for a bit, then comes down to a normal idle and seems fine, there are two main possibilities.
1. The LSN is too lean, richen it more.
2. The idle is set too high. With it at that high idle, back off the idle screw until it comes down to a normal idle. It will probably want to stall then because the LSN is way too rich now. Lean the LSN until it idles right again.
