My saab will start fine when the motor is cool and run normal for 10 minutes before it dies. Then it will not restart until cool again. Fuel pressure maintains a constant 43 psi. It is not showing any codes in the computer. It always runs just for 8-10 minutes everytime. I am open to all suggestions. I have AE but only the generic powertrain for the saab.
Thanks, Mike

Don't wait for it to cool down do below immediately to determine if its fuel or spark that's causing it

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
