Oscillator stops on MC9S08

I am using a resonator 

10.0MHz +/-0.5% Built-in caps Chip type:

Murata CSTCC10M0G53-R0

The resonator is connected in parallel with a resistor 1MOhm and 220R in series.

The chip uses the internal oscillator. The 10 MHz is used for Baud rate generation for the UART.

It happens that oscillator stops.


Any ideas?
