I2C Arbitration Lost errors

Hi All,

 I have my RT1062 setup to be a I2C master. I send out a Read command as seen below, and very often but not always, my master's ISR kicks out an Arbitration Lost error (kStatus_LPI2C_AribitrationLost). Right after it sends the Read Bit, and control is to be handed off to the slave to put the Read Data on SDA. 

Any insight as to what is going on here? Do I have a pin config issue? Or is there a timing issue in the driver in handing things off?
