First have you checked the MAF as these are a common problem on the S4 & RS4.

Next check for leaks and maybe drop in some new sparkplugs or at least check the gapping. I would also check when the last time a Fuel filter was replaced as these can get blocked up and cause running issues and one last thing replace the coolant sensor as these can throw up strange power loss problem and will do it intermittently.

Have you VAGCOM'ed the car as this will show you any faults that may be there.
