This can really only be answered by posting your whole routine with all types of volume/frequency/rest breaks/etc. However, since I don't really want to analyze it....
Generally, people will stall because of 2 reasons:
They're overtrained (in which case a rest break is needed)
Or they've outstripped teh gains of specific statics in which case they need more supplemental work like the pseudo planche pushups or other variations.
So if one doesnt work try the other.
