2006 90 hp 4 stroke EFI

The motor statrs and idles great, but when I try to go above 3000 rpm a steady alarm goes off and the motor shudders. I've replaced plugs, fuel line hoses, filters, thermostat, thermosensor, fuel module float and oil pressure sensor. All of the above were suggested by various repair technicians. Has anybody had a similar problem?
