AD8429 Single Supply Simulation and Design

I want to use an AD8429 as a single supply instrumentation amplifier.  However, I am having trouble implementing the design in both LTSpice and in application.  I'm attempting to use it with a single 12V supply with 100X gain and I'm driving the Ref pin with just a simple voltage divider as a proof of concept for functionality.  However, I get an output with lower gain.  Even driving the pins at the input of instrumentation with half the voltage supply only makes the output a DC 6V.  Is the AD8429 capable of using a single supply in a stable scenario?
