MP3H6115A Failure modes?

Using the MP3H6115A in an altimeter application and we are observing a strange behavior in our test rig.  We are driving the sensor at 3.2Vdc and the output voltage at 101.3Kpa (sealevel) is hovering around 1.5Vdc.  Review of the related circuit shows no abnormalities.  Is this a typical failure mode of the sensor?

-Side question:  We considered using the MPL3115A2 but our current application requires a sample rate > 250Hz is there any way to achieve a higher sample rate greater than 100Hz with the MPL3115A2?

 

-Thank you
