I think I know what is going on... but lets be clear on some things.
1) There is no "ignition" on a diesel engine - as long as fuel is injected and there is air... it will run.
2) The glowplugs have absolutely nothing to do with running the engine. They are only used during starting the engine below about 40F degrees.
Given the above, we can make the assumption that perhaps the supply of fuel to the engine may be a problem. It sure sounds like you are describing EXACTLY what "gelling" of the fuel would do to the engine. (Start fine - run for awhile and quit)
I would suggest you replace the fuel-filter and make certain you have added anti-gell to the fueltank. The WHITE bottle of "Power Service" available at Walmart is a very good product to use in the winter for EVERY fillup. (about 6oz per tank full)
I would expect that to resolve your stalling problem

I'm not understanding why the fuel "jelling" would elimate what I'm calling power to the ignition.
When I turn the key on I don't have power to any of the Instruments and the Engine won't turn over. If you think that this would happen I'll gladly try it.
For the record the mechanic I took it to has an '01 jetta TDI so i would think that he would be aware of the possibility of "jelling."

the word "ignition" specifically means power to the spark plugs to ignite the fuel in the cylinders... but the TDI does not have spark plugs so I was not clear on what you were tallking about and made the assumption that you were not able to get the engine to fire while cranking... this would be EXACTLY what gelled fuel would do.
You did not mention power to the instrruments. Of course this would not be caused by gelling.
With this new information, I would start at the PDU (Power Distribution Unit) which is attached to the top of the battery. Make certain all of the fuseable-links are snugged. Also verify the big red wire from the battery + to the PDU is clean and tight. I would also remove and clean the negitave terminal where it connects to the engine. While you are at it, remove and clean the big red wire connected to the alternator.
All of these points are known to get corroded and can cause all kinds of electrical problems on VWs.
The standard disclaimers of knowing what you are doing while working around a battery capable of 600 amps apply here. (disconect battery before doing any of this!)

Jan 28, 2010 (3:20 am)
'm facing a strange problem. When I cranked ignition on my 2001 Jetta I heard a click sound and complete power was gone. I tried couple of things by checking the battery voltage and couple of fuses there was nothing wrong with any of the parts but there was no power in the car and the electronics were down and I couldn't start the car. When I Checked in the evening again same thing happened. How to resolve this problem?
Problem is same as the problem #22. But there are nor response to this post. I appreciate your suggestion.

Hello! My 2006 Jetta TDI decided to be temperamental this morning and die on me on the highway. It was running fine for about 20 or so miles before it started sputtering. it almost felt like i was running out of gas although I still had a 1/4 of a tank and it was too warm for gelling to take place. i added some diesel 911 to the tank under the suspicion of water in the lines and after several tries, finally got it started again (it always cranked, but did not want to start). at that point, i had warning lights, bells and whistles going like crazy. the oil light came on, so i immediately turned off the car and checked the oil...there was plenty of oil. meanwhile, in additional to the oil light, the emmisions problem light was on, the glow plug light was flashing, and i had lost ESP (stability control) and my Tach.... i was able to drive it off the highway to a place where it could be trailered if need be. we then decided to check the fuses to see if that was an issue. we restarted the car and all the lights, bells and whistles were gone....and the car is running fine...any thoughts, we really don't want this to happen again...

Perhaps some bad fuel... most folks with your type of complaint would change the fuel-filter and hope the gunk in the fuel was tossed out with the old filter.
QUESTION: Do you add fuel-additive at every fillup? if not, why not?
