engine trouble

ok guys this is a complicate dthing for me to explain, so ill try my best. ok, my car runs great, on the high way, at idle, the oils clean, just got new plugs and wires, and changed the timing belt. but it has one bug in it i cant seem to squash. when i floor it, and it picking up rpm, about 50% of the time, its ok, but sometimes, its just give out like at 5-6000 rpm, but only when i floor it, not whne i gradually get up there or at idle, so it has to do with the load. Im thinking that it could be the crank angle sensor since in the past, whne i change dthe pulleys it was giving me the same prob becuz me being a dumbshit left it hanging and the pulley rubbed the insulation off of it and the wire was grounding out the engine. so i picke dthe wire up and got it back where it should be and it was ok for a few weeks. then it started up agin. it feels like i slam on the brakes whne im really gunning, like the engines not getting fuel, but i have a feeling it the sensor, sry this is so long and bless u for reading it...help. TOODLES!!
