Stutters at full throttle, ?????HELP

[429mustang]

The thing is I just put all new bearings in last year, the oil pressure problem just started, although when it drops the motor doesn't get any noisier (lifters/knocking/etc) so it makes me think it't the gauge or something electrical. It's weird cause it all happened about the same time a few days ago, everything went to sh*t and even my starter died during the mess (friday). I replaced it and it starts good, the oil pressure looks good at first, then gets all messed up. It feels like the motor isn't running off all the cylinders, the plugs look good though and everything in the ignition is brand new (Accell HEI/wires). I'd like to get a new carb soon, but I don't want to buy some nice Demon and put it on just to have it still be messed up. I'm not sure what to do now. Maybe I'll just go set it on fore, I had a dream the other night it caught on fire and burned all the way down so maybe it's the vans destiny !
