LMK04828B SPI reads sometimes zeros



We use the LMK04828B for a long time and it worked as expected.

But now we saw a problem:

If I read a register (0x183 or 0x03) every 500ms, the data from LMK04828B is correct. But when I read the register every 40ms, I read frequently zero from LMK04828B.

What is the reason for this behaviour?
Is there a problem with the LMK04828B, or is it a timing problem, or is the LMK04828B in a status where I must not read the register?
I am helpless.

Thank your for an answer
