sudden power loss - Boxster '00 S/Tiptronic

[Steveinsouthborough]

I had a strange thing happen on the drive home from work yesterday, driving my '00 S Tiptronic (which BTW, just had the tranny fluid and filter replaced just last weekend)
I pulled onto the Mass turnpike, and had moved over to the 3rd lane, cruising along at 65 or so., just fine.
I wanted to pass someone, but when I stepped on the gas, all of a sudden there was like very little or none throttle response.
No warning lights on the dash at all
I was able to get over to the shoulder of the road without incident.
I turned the car off, waited about 30 secs, and turned it back on.
Still no warning lights. I proceeded in the breakdown lane to see how it behaved, and it seemed back to normal, so I pulled out and continued on my way, everything again functioning normally (tried in both full auto mode, and also in Manual/tiptronic)
I saw this link when doing a web search on it at
Sounds like could be something to do with gas pedal, though I am not seeing any codes or warning lights. Have any of you folks ever experienced this?
