Clutch pedal get hard to push down sometimes

So just bought 2015 PP GT it's all stock. So last couple of days clutch pedal has been getting really hard I'll pump it a couple of time and it goes away. Will do it at random time mostly when just driving around normal.

Did you ever determine a solution? My 2015 has started to do this, the initial push after cruising on the highway is much more difficult.

First I have heard of this type of problem and I think I have had more clutch problems than anyone.
