Default Need help with L92/Ls3 swap

hey guys, I've been reading on here forever but this is my first post. So here's the deal. I have a 2002 Chevy avalanche that came from the factory with a 5.3 and 4l60e setup. I got a used L92 for a steal, and decided to convert it to Ls3 specs (by removing AFM and VVT) and swap it in. I also went ahead and swapped in a built 4l80e to hold the new power in such a heavy truck. I tried to do things the "easy way" and went with the trg-002 module from LPE to try and retain my original harness and ecm. This swap has been plagued with issues and I've finally hit a wall that has left me unsure of what to do. We have gotten the truck to crank, and start and run. It sometimes takes a second for the truck to actually start when cranking, but it eventually does and will idle a little rough at first, then level out. it will run like normal for about 15 minutes then die out of the blue. whether I'm driving it or its just sitting in park. then it will not restart for several hours. The trg-002 is signaling that it is getting input signals from both the crank and cam, yet when the truck will not run we have idintified a no spark condition. Both cam and crank sensors have been replaced twice. I spoke to LPE on the phone and they told me it soundseems like the box is overheating based on symptoms, but that the box is signaling that it is fine. So long story short, we are pulling the engine back apart to swap the 58x to a 24x and the 4x to a 1x. The goal is to get rid of the second computer system. I need to know what parts I need to order and if the 1x cam gear will work in the L92 block, because the sensor is on the front, not the back, and will the 1x sensor work in the L92 block location? thanks in advance for any help and any advice you have to offer.
