hmm..

Need more information than that.

Does the engine stall out?

Does the power shut off too?

Does the radio turn off?

When you crank it back on, does it hesistate or just start right back up?

Any mods? I know your name is stock...but need to ask.

How many miles, and have you done the services?

Check your battery terminals. Keep your key in the ignition and go up a click. Pop the hood and keep your door open at the same time. Wiggle the terminals somewhat vigorously. If the contact is not good you would hear your door alarm stop for a second or two until it reseated right. Our SCs will cut out on us without the battery being attached and the car is quite dangerous in that state.

Note: If you notice that before your car cuts out you see voltage spikes, such as when having the blinkers on the rest of the electronics go dim, then you do need to check your terminals AND ensure that your electronics are properly grounded. Some here have noticed an improvement replacing the battery terminals with the cable itself as well.

stockSC, does your problem happen while under power or does it just happen while at idle(with your foot on the brake at a light). You should give as much detail as possible to help diagnose your problem. With your milage...I would suggest obtaining the repair manuals. Then you could really troubleshoot any problem., like checking your throttle position sensor.

Hard to tell still. You didnt answer my questions so it would be tough to troubleshoot without seeing the car and isolating the electrical from the engine.

fuel filter or the fuel control ecu. search those items (maybe the maintenance forum will be better). you'll find what you are looking for.

edit: - but this might help

today i take my back seat out and check the fuel pump. it dont have any power goin to it i checked all the fuse none are blown. whats the next thing i can check??

gadgetSC

stocksc....If you checked the fuses and they are not blown the next path is to the EFI main relay. Its in the fuse/relay box on the drivers side of the engine compartment. The power goes from through the fuse to through the relay(If working) on to the fuel pump ecu...from the fuel pump ecu to the fuel pump. Hope this helps.

Take it to a mechanic and ask him to replace the fuel filter.
