Speedie's got it right. It's misfiring - my wife's 2002 does the exact same thing. I replaced plugs and wires and still had same problem. talked to a VW specialist (not the dealer) and he didn't even want me to bring it in - he said he's about 99% sure it's the coil packs. Beetle's are NOTORIOUS for BAD COIL PACKS. I might still take it to them to be sure before i drop the cash on coil packs but then again I might just go ahead and do the changeout.
