0603 code
2002 7.3 starts, run rough then clearsup after a few minutes, goes for sbout 4 to 5 miles then dies like i would have turned the key off, will not start, just turns over, if i wait until it cools it will start then do the same thing. 0603 code comes up. any one familiar with this?

P0603 is the code that says your PCM was modified with, usually by a chip. Its nothing to be worried about.
It is unrelated to how your truck is acting. Until you figure out what is wrong I would uninstall the chip.
I would suggest replacing your CPS (Camshaft Position Sensor)
Could be the ICP sensor as well. Just unplug, look for oil on it, if its oily, its failing. Can run with it unplugged to test as well, it will use default tables when unplugged.
