1998 Oldsmobile Cutlass Supreme mileage: 115,000. This engine will run for thirty seconds and shut off. Then there is no spark. I removed the dies coil pack and ignition module and had them tested, with a good result. The ECM was changed last year for the same problem, but it shows no codes. The fuel pump pressure is around 40 psi, even when engine shuts off. Any ideas where to look from here?

You may be having another computer module failing. Check with an Ohmmeter the resistance of the ground connections to the computer. Also, check the resistance of each of the fuel injectors. If the resistance of a fuel injector is high, it will pull too much current through the computer and burn it out.
