P Channel MOSFET is not behaving with another MOSFET
Q2 leakage is probably through the body diode of the FET, which is not shown on your schematic.  I think a bigger problem is that the gate and drain of Q2 are connected together, meaning you can only get within Vgs(th) of your 3.3V supply.  And Tony's right, if those resistors are meant to turn off the FET in a floating gate situation, they should be connected between gate and source.
