Sorry Siegfried.... both Bobbie and I have noted this phenomenon when trying to do accurate measurements of note pitch on a reed. It is much more noticeable on a wooden bodied instrument than a metal for reasons of heat retension (or at least I believe that is tthe reason) I won't say the pitch takes a nosedive ... but it definately does seem to go down... and it doesn't seem to be due to tired lungs at the end of a blow because it retains it on the next blow if done soon enough.
