I know that at one time, the Series 60 motors were set up to shut down after a certain period of time at idle, and the means by which the engine was able to confirm idle state was the oil pressure. I would not be surprised if your Cummins has a similar feature. The oil pressure at idle is lower than in any normal operating state. The way around this is to to use the cruise control to put the motor on a high idle if you need it to keep running. (As I recall, this was done simply by turning on the cruise while the parking brake was set.)
