Sudden Power Loss

Thanks for the tip on the 'limp mode'.  It's been over a year since I triggered one of those from boost and I'd completely forgotten about it.  Not sure what did it this time though...
I reset the ECU and all seems well again.

This sounds a lot like "limp home mode" - can't 
make more than 1.3 bar as I recall. How's the MAF sensor?

Friday I took the car to work and back, took it out that 
night as well then parked it all weekend.  All was well.
This morning 
the car seems to miss when accelerating.
At speeds over 65 in 5th it doesn't 
cut out until the car develops about 5+ psi of boost.
At lower speeds in 5th, 
50 and under, it is losing power even under light throttle.
In neutral I can 
rev all the way up, only under load does it exhibit this behavior (I feel like 
I'm not describing it well enough, but hopefully I can get this across)
car also idles without a problem.
I blinked codes and the only one I have is 
a 2111 code which is related to RPM sensor.

2111 (Blink Fault Code), 
VAG1551/2 Fault Code Number 00513 RPM  sensor Open or short circuit, 
Defective sensor & cables, metal fragments  on flywheel teeth 

SJM states to make sure that the car is running (which I did) when 
checking codes so I don't get a false 2111 and I don't think that mine is 

Can anyone offer 1st hand experience as to what happens when this 
sensor starts to fail?  Can I get some tips on where this sensor is and 
what is involved with
