I think you may just have a bad ignition switch my uncles 92 Honda Accord was doing the samething and that is what the dealer found it to be. Try turning your ignition slowly to the starter engage point once it starts release it slowly until the starter disengages if the engine runs while you hold the key it is the switch. Its not anymore than 100 bucks at the dealer just for the switch assembly. And its a breeze to put on. Just plugs right into your fuse box.
