95 Jetta GL, 5-speed, 2.0 L, 146,000 miles
Anywhere from 2-5 minutes after start-up, the car begins to shutter and will not accelerate smoothly. Car still runs, does not stall. When I turn the car off, I lose all power -- odomoter, clock and radio all go dead.
Couple things happen from here -- I can remove the key from the ignition, put it back it in, turn it, and the power comes back on, though all settings have been lost. OR, I keep the key in the ignition and the same happens as above when I turn it. OR, upon turning the car off, I only lose power for a split-second, and no settings are lost.
This is an intermittent problem -- happened once last summer, then did not happen again until about two months ago. I can now go up to two weeks without anything happening, and then it can happen a couple days in a row. I thought it was due to cold weather (below 25) but it's been much warmer the past few days and it's been a problem again. I had taken it to the garage, but it was not acting up at that time, so they couldn't help me.
Three other points -- the first time the shuttering happened, my airbag light came on. It has stayed on ever since (while the car has been running, of course). Also, once everything dies and I re-start, it runs fine and does not happen again until at least the next day. Only after sitting for a long period (overnight) will it happen again. And the strangest one of all -- on one occasion, I could not get it to start for almost 5 minutes (any other time it comes on the first time I turn the key) and noticed a very faint humming sound coming from the dash. As it got progressively louder, I put the key in and nothing happened. I then turned the headlight switch, just for the hell of it, and everything came back on!
Any ideas???

I'd suspect the ignition switch.

That was near the top of my list of possible problems. I'll look into it. Thanks.

The same thing happened to me about a year ago. I had the same symptoms as you had. It turned out that it was my catolytic converter that was backed up, as well as a faulty distributer. I don't know if they were correlated or not. But that did fix my problem... good luck.
