I have managed to get RMS component stresses out with: STRESS(SORT1,PLOT,PHASE,CORNER,PSDF,NOPRINT), although not VonMises. I use FEMAP 2019.1 for post-processing, if that helps.
Nastran does not calculate the VM stress PSDF response. MSC Patran Random tool will allow you to do that. But in that case you are running random outside of nastran.
