Ignition shutting down under heavy accel
 

I'm having trouble with my car while under heavy accel in 1st and 2nd gear. The car is shutting down,engine light comes on, gauges go dark at night. I'm just back into the rotary thing after having a modified 1st gen car, this one is obviously much different. I have the crane igntion system and I've been looking for a loose or frayed wire that could be causing this problem, possibly when the motor torques over while under accel.. I was hoping someone could give me a direction to look in before I have to resort to an electrical shop. thanks in advance for any help ! ! !
