I'd say the odds are about 100 to 1 that the crankshaft position sensor is going out on you. It is sometimes abbreviated as a CKP sensor. This happened to my father's 2001 and another symptom it would show was the tachometer would drop to zero. I drove his 2001 for a while as I tried a couple things to diagnose it. Typically, if I was driving over 50mph when it happened, it would just kill the tach but the engine might keep going, and the performance would decline - engine would ping and "service engine soon" light might indicate a problem code. If I was driving under 50mph, it would sometimes just kill the tach, but would also frequently kill the engine.
Someone in New Jersey tabulated the failure of the CKPs and if I remember correctly, there was a batch of them manufactured during a portion of 2000 that were 4 times more likely to fail than other dates.
My father followed up on a lot of advice, replaced numerous sensors that were supposed to be grounding the computer, or indicating a high temp to the computer. But when he finally broke down and replaced the CKP, the problem went away. The part costs about $25-30 at Advance and he had a small front yard mechanic install his for about $50. Most won't install it that cheap, it is about an hour to hour and a half job to replace it.
He's happy with it now, and feels comfortable driving it on 2,000 mile trips again. He just got back from one.
You can search the net and find some people have sites that have pics from when they changed their's out. Very common engine. The service manual says you need to have the computer 'relearn' something when you replace the CKP, but I'm pretty sure this guy never did that. When I've replace the CKP on other model cars, there was never a 'relearning'. Just install and go.
If you have your CKP replaced and that fixes it, please write back for future readers.

The dash warning lights for the ABS system and Tractkion Controll Off lights come on and remain on when the vehicle ist started. If I turn the engine off they go out about half the time. Any suggestions at to what the problem may be

Thanks for the info. It was a great starting point. We did check the crankshaft sensor and found it to be OK. I was also told sometimes the waterpump can leak and short this sensor out, but we found no leaks.
However, something I didn't think about was checking the fuses. I had a bad key chip and thought the problem might be in the ingnition switch even after buying new keys. What I found was that over time the fuses had vibrated part way out with the ingnition fuse the furthest out. These were tightened and so far I have had no further problems. Thanks again.

Took the buick back to auto repair and they checked it out because it was losing 4 mile per gallon after tuneup and they said they didnot look at the update bulletin, so this time they did look and say they think they found the problem after the tuneup and fixed the problem. Too soon to tell.

Did they say what had been done wrong or what was missed that would cause a drop in mileage? I am finding that hard to believe that there was something in a bulletin...
