High RPM/High boost cutout usually indicates a spark problem to me, but I
thought a spark problem should get worse, not better, with low
temperatures and high humidity. It also wouldn't explain the coolant issue
that seems to be related.

With the coolant event you describe, I'm tempted to say that some seal is
separating just enough to let some pressure out at extremely high outputs
and high temperatures.
