BQ51050B: BQ51050BRHLR connection to transmitter is in short spurts

Part Number: BQ51050B

I have a BQ51050BRHLR connected to my transmitter design using the NXQ1TXH5.  The transmitter is inside of a re-charging cradle. The BQ51050BRHLR unit is then inserted into the cradle for recharging. Thus, the orientation and distance between the coils is fixed.  The BQ51050BRHLR always connects right away, but it will disconnect and then reconnect.  I have the FOD on the transmitter disabled.  I've attached the design and images of two graphs of ilim voltage vs. charging current.

Do you have any suggestions? 

Thanks,

Steve
