sudden lack of of connection?

[Flagracer]

Hello all. I got a Hyrda approx 6 months ago and the install and programming went perfectly and the truck ran fine since then. Just the basic 4 codes for a 97. Recently I started it on a cold morning to warm up for work. As I walked away from the truck it died suddenly. I restarted it and drove to work fine. I went out at lunch to start it to keep it warm and now it cranks but no fire. That day I did the Cam sensor because I figured it was quite old and hoped that's all it was. No help.

Now I notice there is no light on the control pad, no numbers are lit. I have removed the housing completely and cleaned all connections multiple times and tried the alternate cable/head unit for the pillar. I have checked all the fuses and all are good. How do you determine if the Hydra itself is bad? Or if power is going to the computer to even get to the Hydra? I've looked at the pin outs on the web and can't see a specific power wire labeled as such if there is one.

thanks for any help
