The ignition switch. Where the key goes in is the key tumbler.
A ton of Buick and GM owners replace the ignition switch so that their cars won't cut out and KILL THEM.
I had the same problem with my 98 buick regal gs and it turned out to be the ignition switch.
I believe that the switch is located in the ignition cylinder (which you can get from any auto parts store). Unfortunately you'll need a steering wheel puller and a tilt removal mechanism before you can start with that.

My experience with a faulty ignition switch on this generation Regal include random warning lights coming on together and turning off at the same time. Eventually, the car will sometimes stall when the turn signal switch is used. This is due to the turn signal switch "bumping" the wires leading into the ignition switch. Apparently, the wire connections inside the ignition switch sometimes tend to loosen. Dealer cost runs around $350 to $400 to replace.
