I had a similar problem to this one, my main relay went out and would only start if I let the engine cool down. Turns out the chip can expand away from the solder points, so cooling let it connect again. I would replace the relay. Also make sure to remove your battery cables before installation to avoid blown fuses (that one was embarrassing).

If you have replaced all relays then the problem could lie in your ignition system. I would try these things then get back to me: Jump the car after a failure, Try tapping on the starter without damaging it while a friend turns the key, test your starter solenoid with the car off (you should hear a click), check to see that your alternator is working properly it should give off more than 12v while vehicle is running.
