Temporary Loss of Reception

I have three DWM1000 modules setup on my workbench. One module is transmitting messages every 50mS or so. The other two modules are in receive mode. When they receive a message, they transmit an acknowledgement back and then go back to receive mode. Every once in a while, one of the receivers will fail to receive any messages for a period of 0.7 to 2.0 seconds, after which it begins receiving messages on its own just fine. I have queried the system status, and it is in receive mode the entire time. Meanwhile, the other receiver is receiving messages just fine. Has anyone experienced anything similar?
