Car dies at high rpms - need help deciphering composite log
I am hoping much smarter people can help me out. I changed my timing belt last weekend. It idles great. Drives fine until I get under boost. I am running a Megasquirt MS2 Enchanced with a rotrex supercharger. I am also at elevation and make about 9 PSI. I checked the gapping on the Crankshaft Positioning sensor and noticed it had a very large gap. I used a credit card to reset the gap distance. It didn't fix the problem. I swapped out spark plugs, also didn't solve it.
I took a composite log. Not getting check engine lights. Car just dies. I am able to restart it after it sits a few seconds. I am attaching the composite log and tune.

Just went outside to try and start it. It wouldn't. Got my laptop to do a composite log and it was able to start. But here is a log of the start. Thinking it might be a camshaft positioning sensor?
