My 1987 Buick Century will die while running at full throttle. This usually occurs after it has been running for several minutes. Sometimes I can keep the gas to it and it will pick back up but at other times it completely dies and it won't start again for several minutes to an hour.

Could be caused by one of the following below

Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.

Note:If it doesn't apply disregard it and keep testing.
