Cold start running problem

I have a C320, 2001 which fails to restart after initial starting. I start it up cold and drive about 2-3 miles , shut it off , then I have to wait about 20-30 minutes before for it will restart. Any help with this problem. The battery is not even 3 years old

Two things could cause this problem. Either the Fuel pump has finally taken a dump or the fuel filter needs to be changed out.

Ditto to CPS/KPS aka crankshaft position sensor. CPS is also used to abbreviate the camshaft position sensor which adds to the confusion. Your symptoms sound very much like a lot of other people who have experienced a similar problem.
