Here's the story in the hopes it may help others who may experience a similar issue.
I took it to a Cummins Service Centre who was very good at diagnosing and keeping me informed of their findings.
Here is the short version.
In taking apart the front access to the genset it was ultimately discovered that 2 wires related to the genset fuel pump had been pulled out of their connections. This due to the wiring harness being not being ideally secured and with some bouncing as we travelled over time they ultimately pulled right out of their connectors.
This made the control board try to compensate for inadequate fuel and ultimately it failed. Additionally an actuator was sticking and it was also replaced. Once both parts were replaced the unit ran well and produced power exactly to spec' during long tests. Problem solved however it was a pricey fix.
Check your wiring harness if you can to ensure you can avoid any wires being pulled out over time which could avoid a costly repair.
Safe travels!
