Sounds to me like the SW cannot handle the reapplication of the 5V. I think it supplies an interrupt to the processor when 5V is reapplied Check the datasheet of the TPS65217C. If it does, all SW thinks is that the power button was pressed and that you want to power down.
Bottom line is I think you need to so some SW work to make this all work.
