Thanks to tool_king. With his help and support, I found the problem with my EX120G-3. I did discover a way to read codes from the computers without the Dr EX. It led me to the failure of the harness between the pump pressure sensor, the boom extended sensor and the PVC. Repaired the harness and it is good to go. The issue was stalling of the engine when the boom was fully extended. Also, any loading of the hydraulic system dragged the engine down. Turns out the pump, without the sensors working was full swash plate at all times, i.e. stuck in high gear.
