Any way to confirm SC clutch is the issue.
The common cause is an intercooler pump that has failed and the coolant gets too hot, usually that means the car runs fine from cold but when it warms up the SC quits working The air entering the engine gets too warm. I cannot see the SC clutch causing that problem unless the electro magnet is failing, causing slippage.
Check for engine error codes and see if the pump is working, how many miles on the car?
