2000 Hyundai Tiburon

Engine Performance problem
2000 Hyundai Tiburon 4 cyl Front Wheel Drive Manual 182000 miles

the car runs fine untill it warms up. After about ten minutes of driving it will loose all power as soon as I slow down or come to a stop. It wont start untill it cools down again but after that it starts right up. The check engine light is on and I had the codes read. I cant remember the codes but they were: #1 cylinder missfire, #4 cylinder missfire, random missfire, and crank position sensor curcuit A. The timeing is correct and I just gave it a full tune up including o2 sensors. Im just wondering if a crank sensor would have that effect on the car when it gets warm or if it could be something else. Thank you.
