We have a 95 safari dp with Cummins engine
We have a 140 amp alternator and a 200 amp isolator
The isolator has to be equal to out larger than alternator output
Staring out with a low house batter bank they can take all the power the alternator will produce and you can burn out the diodes in the isolator
What is the voltage at the engine battery with engine running
(When you have the problem)
It sounds like alternator over heat and shut down
When this happens you start running directly from battery, not alternator
When the engine battery gets low systems start shutting down
Like the transmission controls and the fuel control valve for the injection pump
A bad aka shorted battery engine or house can cause an overload on the alternator
No dc power while plugged in is another clue, maybe blew a main fuse in the power circuits ? Inverter/converter not charging, bad battery blown fuse
Track down your electrical and I think your power problem will be fixed
