Well Ken, I didn't want to start a new post because I have pretty much the same symptoms and problems. As mentioned, I went by the schematics and checked everything. This time I instantly looked at the ICM connector and saw that it once again melted around pin P. I cleaned it up and got a good connection and it's back running. Prior to it stopping all together after it warmed up it would run rough. I learned that the coil for 2 and 5 was not firing so I swapped the coils around and none worked in that position. I swapped the ICM, and the vehicle ran smoothly up until it got back to the cranking but won't start issue and at the point is when I cleaned the ICM connector and it's running in its current state. I need to find out why what is getting hot causing the connector to melt at pin P. I will include a video of the vehicle running rough before changing the ICM and smoothy after changing it. I will also include pics of both the original and new ICM connectors with both showing signs that they have gotten to hot. When it was running rough I did finally get a P1374 code for the CPS. I included pictures of both the original and new ICM connectors with both showing signs of getting hot and videos of the vehicle running rough before changing the ICM and smoothy after changing the ICM. It will currently start and run and idle smooth as seen in the video.
