It could be....since when engine warm may take a bit more current to move the Solenoid and as such may be beyond the capability of the clutch switch to handle that current. In other words you have less voltage at the Starter Solenoid because of the greater resistance in the Clutch Switch Circuit at a time when the Solenoid takes a bit more voltage to function when engine warm.
