When it doesn't start, is the starter doing its job to start the engine or is there nothing happening? When this happens, have you checked to see if there is spark and fuel to the engine?

Nothing at all it's like the ignition is unplugged and minutes later it will start right upas if nothing was ever wrong

Try switching the starter relay with a relay with the same part number in the relay box. See if that makes a difference.
