I purchased my 2002 a4 3.0L, 6 speed manual about 6 months ago. I have never driven a car that has been as much fun as this one. About 3 weeks ago I noticed that the traction control would shut itself off and then the cruise control would stop working. Once I shut the car down and re-start it everything works just fine for about 5 miles and then it shuts off again. Sometimes I can feel the fuel injectors cut out when in 2nd or 3rd gear at about 3500rpm.

Is there something wrong with my computer? Any thoughts would be great. Thanks.
