Runs great when cold. Misfires when warm

So my 94 dakota with the 3.9 has been giving me a problem. It runs great and buttery smooth when it is cold start but after ten minutes of driving it misfires really bad and sometimes stalls out. Recent parts include: Cap,rotor,plugs,wires,coil Timing cover gasket(coolant leak) Water pump(coolant leak) Coolant temp sensor I was looking into a crank position sensor as the wiring looks sketchy. Also gunna start at the throttle body as well. I do get a code for the coolant temp sensor but... Runs great when cold. Misfires when warm
