When cold the engine funs fine but when it warms up it starts to miss and surges the warmer the engine gets the worst it gets till it hardly runs,dies,surges and will not accelerate.

problem indicates electronic component failure due to heat from current flow
run the fault codes to determine the area or sensor that has failed
could be a cam/crank position sensor , ignition control module , coil,even the ECM

sounds like you have a very dirty mass air flow meter. invest in a new one and be sure to clean the throttle body with an appropriate cleaner and tooth brush.

the ignition coil would not make the engine sieze up, more likley that the car had no oli or the heatgasket caused this
