Sure does sound exactly like what I saw when the secondary fuel pump stated failing intermittently. All was fine for the first few WOTs but just like when the vacuum pump works at 50% when an extended WOT happens the 42 gets set.
I eventually attached a pressure gauge and routed it up to the windshield so I could see it drop during the WOT. It dropped to 44 when the code set. A good secondary pump keeps it at 50 or so.
Good luck
