My 1989 Buick Regal3.1 keeps dieing, what could be wrong? on 1990 Buick Regal

I have 1989 Buick Regal, 3.1 ,last year I changed the ful pump and the fuel screen . Thaen this year it started missing real bad , so I changed the plugs and the plug wires, and it ran ok accept no power , so I put fuel injection cleaner in it and a new airfilter and it will only go 15 mph for about 15 min then wants to start dieing out.

Sugar, you changed the fuel pump last year...maybe it is failing again? or possibly the ignition control module is going bad.
