Default Sudden no start issue, please help!

I just got my new Stage 4 T-56 installed in my Formula yesterday and was driving it around to get some mileage on the break in when I stopped at the gas station for a drink. I was in the store maybe 2 minutes and when I came back out, the car would not start. It's getting fuel for sure, I checked twice. It's just not getting spark. Previous to this, the car would randomly not start every so often, but if you left the key on for a minute, it would start right up. Well, this time it would not. I tried everything. Disconnecting the battery, removing the PCM fuses - nothing worked and I had to have it towed. The only two things I could think it might be are a malfunctioning VATS system, or the crankshaft position sensor failed. If anyone has any other ideas OR if they know a way I can diagnose this without a scan tool, please let me know. I have been without this car for a YEAR now and I really want to drive it before the snow flies. Thanks.

It's a stick shift... so it has a clutch switch and that works because it turns over, just won't fire.

Do they really fail that abruptly?
