S600 only cranking

Hey!
When my car gets warmer or achieves work temperature, then it stalls or only cranks when I want to start, no fault codes but ecu don't see engine speed then, can it be bad crank position sensor?

is there an engine code ? are you able to scan the vehicle? it is most likely the crank shaft position sensor. the code will be something along the lines of “Cam sensor L5/2 signal not recognized”
