The board currently is being used by the team with the EPCS4 prom loading the FPGA at startup.

Ok, that is good to know.

My board has been modified to move to loading it with the MPC8309. So we have been able to program it, but to reduce board cost we are moving the the micro loading it and removing the EPCS4. I am seeing if we still have JTAG access to try this method.

You could also replace the EPCS4 with a lower-cost part. These parts are rebranded Numonyx (Micron) devices. Spansion devices also work.
Regardless of that fact, there should be no reason you cannot PS program the part. Check your MSEL settings, eg., check any logic high levels are pulled up to the correct voltage (I think its VCCA).
