It could be the start solenoid. My problem was intermittent. Would only start when cold because the soldering points inside the solenoid were loose when hot as they expanded. When cold the solder points contracted and were ok to start until it got hot again then if I turned off the engine it would not start again until cool again. You may have the opposite that the solder points only make contact when hot but when cool they do not make good contact
