Oh man...The amount of things that it could be really are high. I've used a good chunk of these mods and can tell you a good portion can cause crashes. The Enhanced Shaders seems to cause crashes on some machines, mine included. It looks like you're using a few different overhaul mods which might introduce an incompatibility or two, though I'm not familiar with FOOK in NV, so take that with a grain of salt. Unlimited companions....Using more than the default is known to cause issues for some people. I notice you're using a DOF mod with the enhanced shaders, but the HQ and UHQ both come with a dynamic DOF if I remember correctly, so that might be causing an issue. Wasteland defense caused crashes on my machine more frequently than normal, but not too often. Electro-City is known to cause incompatibilities, apparently with A World of Pain.

Any one of these could be the problem. Try getting FNVEdit and make a merged patch. That might fix a few things for ya. I can't really give much beyond that though.
