MicroSquirt keeps cooking the wasted spark, Can someone help me look at the datalog? Options

I have been trying to get the car ready to take Red Rocks and Okteenerfest. So far the microsquirt system has been pretty great but has some issues to get worked out. From day one the Air Fuel Gauge for the O2 sensor had an issue. It would mostly just flash 7.4 but would seem to give some readings until it warmed up and then just flash 7.4. However, it was able to be tuned in tuner studio.

We also had an issue with the ECU losing connection with the crank trigger/hall sensor and restarting. We believe that it was in the wiring the for the resistor on the hall sensor that was causing this. What would happen is that it would run great until it got hot and then it was like someone was flipping a light switch on and off very quickly. each time it would come back on, the ECU would think it was starting the car and adjust fuel and dwell ect and the car would just bog out and not run. Then it would eventually kill the wasted spark. I could replace it and it would start back up but would repeat the problem.

So The day started off well yesterday. We replaced the O2 sensor and finally got the gauge to work. We (Cary) had already rewired the hall sensor with a new resistor and the car had been starting and running great but had not been road tested yet. I was hoping that all issues were now resolved and I could schedule some time on the Dyno to get the fine-tuning done.

I took the car out to try and recreate the conditions where things were previously failing. I made it all of about 7 miles, with the car running better than it ever had before it just stopped running.

I looked at the gauges and the Coolant temp gauge was red and showing 240 degrees. The "Coolant temp" is really the air temp measured inside of the throttle body. The temp did not feel that hot and I have never had it go that hot that fast. I did not hear any backfiring. I took the rain hat off of the Throttle body and it did not feel that warm. I had some air in a can (for cleaning keyboards) and I blew it on the coolant sensor and did not see a drastic change like I was expecting. It slowly came back down to where I previously may have been able to restart it. But I had no spark again.

We got it back to the shop and I replaced the wasted spark for the 3rd time now. It fired right up.

I was data logging and captured the event but I am still not very good at reading the logs. I didn't,t see the "flicking on and off" like we did before when the wasted spark was getting cooked, but it does look like something is happening with the dwell.
I have the log in a drop box folder here: https://www.dropbox.com/sh/3osmebnfu61632k/...sSkTj-tlFa?dl=0

Can you take a look at it and let me know where to go from here?
