You may need to change your spark plugs, wires, and possibly the distributor cap and rotor button. Old wires will "leak" electricity and can, in a sense, short each other out. The faster you try to get the engine to go, the more electricity from the wires gets grounded or transferred to another wire, throwing off the spark timing to each plug.
