Thanks for the help, everyone. Think we found the problem. Bad MAF sensor. Took it off and car stayed on just fine.

Thanks Bright1! We tried and installed a new crankshaft position sensor today hoping it would work, however, sadly it didn't. The car still has no problem starting, just wont stay on. Very frustrating! Other ideas we may have are idle air control valve, fuel pressure regulator, fuel pump relay/fuse, or someone we know suggested the timing belt.

Hi everyone, new to this. I have a 99 Subaru legacy GT limited, 2.5 L. Recently it began to idle low and die when stopped. It was fine while actually driving. We changed the fuel filter, fuel pump, and air filter. Now, the car starts, but won't stay running. It dies after a few seconds. The check engine light is on and the code that came up for that was the knock sensor, but from what I've read, it doesn't seem like the knock sensor would cause it to not stay running. Any ideas would be appreciated.
