WAS DRIVING ON FREEWAY AT 65 MPH AND IT JUST STALLED. PULLED TO SIDE AND IT WAS RUNNING ROUGH FOR A FEW SECONDS AND THEN QUIT. COULDN'T GET IT TO START AFTER THAT. I DISCONECTED FUEL LINE BEFORE FILTER AND TURNED KEY IT IS PUMPING PLENTY OF GAS. REPLACED FUEL PUMP LAST YEAR. THE MOTOR WAS REPLACED 3 YEARS AGO WITH A CRATE MOTOR FROM GMC BUT I HAVN'T REPLACED ANYTHING SINCE.

Could still be alot of things. Primary voltage, Distributor, ECM. However the ignition module failure is common on these vehicle. I would start there next.
