Do you have substantial play in the top bush of the distributer. I did, and it caused a similar problem. Once the engine was nice and warm, the points gap reduced to a stage that they didn't open. Also check your points are clean, I once had a problem where the engine would start, run but after several miles would all but stop. Had to get towed home, and after cleaning everything fuel wise found pitted points - How embarrassing !
