Low voltage rest problem - MC9S12XDP512

Hi, I have MC9S12XDP512 in my project. When using the pseudo stop mode and the PLL, bus frequency 40MHz, because of time demanding calculations, the instrument accidentally restarts, after about hours. After the reset, the register CRGFLG contains the value 60 decimal, which means a low voltage reset. If I use WAI mode and not use PLL, the problem does not occur. Can you give me an advice? Thank you.
