7.3 crank no start after just driving
 

So I just came home from work 22 mile trip so engine was nice and warm I think I've been having trouble with my ts 6 position chip so I drove home on stock and was driving fine until half way home cruise was set 70mph and it seem like going down hill I had a miss and truck would jerk but driving uphill would be fine and flat would barly do it, so I got home took out my chip out(key not in the ignition) and then tryed to start it and it wouldn't my oil pressure gauge also does not come up with 4-7 seconds of cranking and then when I felt my PCM it was super hot. Any ideas about this? Also where is the IDM (injector drive module) or is that and the PCM the same thing? Any input would be great! Thanks
