I have some experience with my oldie cutlass 90 that I had import to my farest country : CHILE .
My car seemed to run in three cylinders , of 4 .then started to run good in cold and after 10 minutes stop and die for a long time ...a few days after strat again and dies and so .. I studied about I read about the prom I learnt all abo¡ut this kind of irregular fails that even experiencied machanics can´t solve ...( It took 6 months and seven mechs to solve )..
the cars falls in limp in mode ( a kinda mem programmed mode for a few minutes and everybody thinks it the crankshft sensor , the ignition module , the ecu fial etc simply is code 51 : mem cal fail and limp in state i suggest work with and a code reader and it could be that kind of irregular fail..
ah. it´s too hard to find the eprom so the ECU dealer usually sell it without the eprom .. mine is ANLP 3645 ) federal emission .if you know when can I buy this or a good used one . I ´d shop it again cause I don´t want suffer about it again.. luck

sounds like could be a carb providing an excessive amount of fuel any signs of black smoke from exhaust ), overdue need of spark plugs, or if everything proves ok, a faulty ox sensor
