Question about 1999 Buick Regal
Replace the fuel filter. If that doesnt do it which it probably will, make sure the fuel pressure is consistent, as it could be a faulty fuel pressure sensor.

I had a problem on my Nissan Xterra 2000. Symptons sound similar. In my case, it ran fine for a while and then suddenly the engine starts to stumble and lose output. At one point it did not even have enough HP to move. Irregular idling too. Thought it was water in my fuel. Bought water remover from the store and added to gas tank. Problem did not go away. Instead, "Service Engine Soon" light came on. Had to have it towed to the dealer as there was no way the engine could keep up with traffic. Dealer replaced the "Crank Position Sensor" today. Parts $33.00, Labor: $300 (about 3 hrs worth of work). Seems to work fine now but I will wait and see. Dealer also stated that Distributor bearing appears to be noisy and will need to be replaced sooner or later. I will wait for it to go before I fix that.

Have a performance diagnostic performed. And run the LOWEST octane that your car allows. Too high octane lowers performance with the slower burn, essentially less voliatile burn.
Check tire pressures and driving habits.
