Is this a 'drive by wire' vehicle on 2001 Mercedes-Benz SLK320

After car has been run for a couple of hours the following happens: come to a stop, press on the gas and nothing happens. No rpm increase, nothing. Then all of a sudden it will take off.

It does have drive by wire throttle. Don't jump to conclusions it is faulty without properly testing it. The unit from Mercedes is $1000.I am sure it is available aftermarket but get a good independent Mercedes repair shop to check it out and test it first.
