454 mpi cutting out.
It idles fine, comes right up on plane but about 3200 rpm it just dies. pull the throttle back and it runs fine. Cuts out if you run the rpms up in neutral or under load. What to check??????

First I'd check fuel pressure then cap and button just for simple things first off

Seems a bit like power reduction mode (that'll let you go to 2800rpm then will drop 4cyls until it's below 1200 rpm--or something like that). I'd also suggest checking timing and condition of cap/rotor.
