Answergotta be a short that is shutting down spark. Look closely at starter circuit, and wires around distributor. Also check ground strap from battery Something is moving when the car is up and flexed which then eliminates the short.
I gotta admit, this is first for me, and I have seen and heard a lot. I feel certian it is a short, just gotta find it .
I had an old 220 that had worn a slight open area in the wire from the condensor, it was touching the distributor case and shorting the whole thing out. Took me a week to find it, I looked at it 20 times (lol)
