Holds a strong idle all the way until the engine is hot, and the whole drive, everytime I take it out of gear the revs drop way down and hit 6-700rpm. Three times its conked out. Anyone experienced this before?

Once warm try adjusting the idle screw on the inlet. Set it to somewhere around 800rpm and see how it goes

If I do that will it affect where the car idles at when I start it cold. Like I said wen cold it'll sit at 2k and gradually come down with temp omcrease. If I do as you say and raise the idle up a little furrther when warm, will it also raise the rev went it starts from cold again - from 2k to anything above?
Or is it an automated clutch that makes it hold at 2k when cold do you know?

on top of the trottle body is a smal black round rubber stuck in the hole of it just take it out and adjust the idle when the car is at full temperature set it to 85o/900

Also check the tps is showing closed when the engine is warm, the idle control valve does not operate unless the switch is closed.
