WEP shouldnt switch itself off.......instead the engine should just get hotter and hotter and hotter......you'll eventually (and I'm not talking a mere 10 minutes here) start to hear a ringing sound as things start to melt.......then a gradual power fade until, finally, something important melts.....and either the engine suddenly seizes or a barrel gets fouled by a lump of molten piston ring or whatever......and then detonation occurs.
