Pulled the OVP relay and that seems okay also although I didn't take it apart to check solder connections

If disconnecting the EHA allows it to run ok, then the OVP is not the problem. The principal input used by the electronics to control the EHA is the O2 sensor, so I would first suspect it is indicating a false 'rich' reading - i.e. not working.
