Interesting that your latest gen rocket doesn't have the run dry (which ain't really "run dry") capability of my 50 year old SK61.
The N model had something called emergency lube. It consisted of an overlarge transmission sump designed such that the bottom part (5 gallons I believe) could only be accessed by a little electrical pump. So, you can piss all the oil out (happened to me in the Beaufort with a frozen vent) and when the pressure drops below a set value (8 psi as I recall) the pump comes on a lubricates the critical bits.
This system has been proven many times to last a lot longer than 30 minutes. Some claim it will go 3 hours but I don't think I would want to try that
