Irregular wirelessly connection between 2 Xbees

Hello all,
I have a strange problem. I hooked up a magneitc sensor to a Xbee pro, transmitting data at 868 MHz. The radio and the sensor is programmed to send data continuosly.
On measuring the received data for 2 days I find that the wirelss link is irregular.
Data is received wirelssly for a fixed amount of time, the communication stops and resumes again after some time.
What can be causing such kind of behavior?
Has anyone experienced this with the Xbee pros?
