Sent box to Mallory they say no issue with it box is good and they had no issues.
Car will start run then at a random time box (LEDs) blip off momentarly enough to kill the engine at idle.
 It will run fine (great even) with box bypassed does not miss a beat, but since the tach is hooked the box running this way I have no tach nor the features I want off the box such as start retard and rev limitor. I would love this thing to run correctly.
I am out of ideas have to assuse box and box wiring good just checked out by Mallory. My wiring to the box I would think is good since I can run bypass with NO issues. What would cause it to flake out blip momentarily ?
Any ideas what may be going on ?
I am going to try to short the ballast resistor and see if that will do anything
