I had the same problem with my 1988 Oldsmobile Delta 88. Replaced fuel pump and Ignition control module. So far, there is no cut off. You probably have no good Igition module.

same thing happened to my 94 LeSabre. It happened from time to time with no "Service Engine Soon" indication. Eventually I got the indication, it was the EGR valve.

Does it start right back up when ever it cuts off? check the battery terminals first, jiggle them while the engine is running if that didn't afect the engine, it sounds like the throttle position sensor is faulty. change it.
