darn electrical

Did you do any recent electrical or ignition work on it recently? Sounds like loose connection or bad ground.

Not really I felt around the neutral safety switch to see if it had the 3 prong connector on it { it did } as the back-up lights I made for it last fall have never worked and I wasn't sure if they were wired at the tranny or not ,pulled the passenger side valve cover off to check for a loose lifter which may have jiggled something at the coil , I am leaning towards a buggy coil or control box as the car has had some rough idle issues from time to time lately and has been slow to fire when hot which I thought was a fuel boiling issue but who knows maybe I'll buy a new sew of plug wire's ,coil and box, since I'm getting ready to buy/build a stroker and would like to make sure everything I bolt on to it is good .I guess I'll be unwrapping, checking and re-wrapping the engine bay harness while the motors out for sure now eh!
