runs rough and misses

My a 86 Crown Victoria starts fine but misses a little then it will die after a couple minutes of running. Starts back up fine. When driving I get to around 35 MPH and going up hill or down and try to accelerate it gets a jerking motion, and it sounds to me like a miss in the engine, but if I put the peddel to the floor it takes off and runs great.
I have had it to my mechanic but he couldn't find the problem, recomended that I use higher octane fuel. And I do but is hasn't helped.
I have new , points, rotor, condensor, plug wires, new exaust system front to back. any help will be appriciated

Re: runs rough and misses

It might either be the magnetic pick up in the distributor or the timing chain, at low rpms it will through the engine brain off time. I just now put a msd HEI distributor in my car and smoked a set of drag wheels, run great at low rpms, it was doing what you described.
