LTC2944 Voltage Reading Anamoly

I have a setup where I use the LTC2944 to monitor the battery voltage and the output of which goes to the microcontroller so I can use data logging to monitor the voltage and log in every second. I have used this setup successfully from -40C to 21C without any issues. However, when the I test the same setup at either 49C or 60C, I get some weird readings for one or two data points which are way off than normal. The section of the graph below shows an interval of 30 minutes, between hour 1.5 and 2 during the process of data logging. In the table below, I have included a section of the data. As you can see from the bold data points its way off from what its supposed to be. Is there a know issue with this part at higher temps. Please Help!

Thank you
