R32C (R5F64112) device continually resets after loading program with E30A emulator

I have been experiencing continually resets after i download my program and run. This is a new issue, as i have been able to use the emulator for ~2 months without any problems. I have confirmed this issue on two separate units. I am able to connect to my device(s) and download my program, the issue occurs when I run (select "GO") my program. It will reset over and over and HEW says it loses communication.

Things I've tried:

  1. Cycled power to the E30a emulator.
  2. Restarted my computer ( :-) )
  3. Verified the NSD line (no shorts, etc.) on both units.
  4. Reverted back to an older SW build, same issue occurs.
  5. Tried multiple addresses for "Work Area For Monitor Program" setting on the MCU "Init" window tab.

I have ordered a replacement 50 ohm coaxial cable to see if that resolves the issue. Any other suggestions? Has this happened to anyone else?
