I am having the exact same problem (ignoring choppy cutscenes). I can kill revolver Ocelot, and then the emu either GPF's, or just crashes back to my desktop. Any help is greatly appreciated. My set up is as follows:
System
OS: Win2k Pro SP2 DirectX 8.0
CPU: Athlon 800

Video: Radeon 64 VIVO
Sound: SBLive
Settings
Sound: Pete's DSound 1.11 (everything enabled)
CDROM: internal, but I'm using an ISO
BIOS: SCPH1001
I've tried several Video plugins. Here's a sample of my settings:
