One other possibility is that the catalytic converter is somehow plugged up so bad that there's no air flow. This renders the engine sluggish at higher speeds, and can cause the engine to sometimes not run at all.

check crank sensor,and ecm. Both by just tapping on the sensor (wooden dowel works good) with the car running. Kinda hard to get at ,behind the front lower pully,be careful,taking the serp belt off helps .If the sensor is bad it will stumble or quit when you tap it . Same with the computer,should be able to get at it by tilting the glove box door down.

1995 Buick LeSabre - Stalls then restarts while driving

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.
