Okay, After reading about other problems with stalls even though my symptoms are different, I decided to disconnect my EHA Valve. The engine ran fine and I was able to drive it without it losing power. Built a test harness and performed test on EHA and seems to test okay. Pulled the OVP relay and that seems okay also although I didn't take it apart to check solder connections. So if it's not the EHA or OVP, what else can it be? Before disconnecting EHA, I was not getting any computer error codes and now the only error is the EHA one because it's disconnected. If you've had this problem before, please help. I hate to purchase and replace parts on a trial and error basis as these are expensive parts and I'm currently unemployed.

Thank You.
