My suggestion would be to check the ignition coil. Immediately after it quits, before anything has a chance to cool down, check to see if you have spark. If not I would suspect the coil being bad. Doesn't happen very often but occationally one will form a crack somewhere around the windings. Too microscopic to see but as the coil heats up the crack starts to expand and develops a short to ground which effectively turns off the ignition. After everyting has had a chance to cool down it closes back up until the next heat cycle. Just something else to consider
