FiTech EFI system

Got my system installed and fired up for the first time tonight. Not using timing control yet. Took 2 times to start, hunted for an idle and smoothed out quite nicely. It ran for about 10 minutes and died suddenly. I have not been able to get it to start back. It will crank and fire for a brief second and die.

Thanks to the Facebook group I think that it fires on the prime shot, then the pcm isn't receiving a rpm input from the msd box and so it stops fueling. I have checked my connections and even re-soldered my connection and nothing.

Hoping someone here might have a suggestion.
