1993 Bonneville SSEI won't stay running

[mnchevrolet]

few months ago my car quit and had low fuel pressure so i replaced the pump and filter. after that it would run ok sometimes and not ok. i don't trust it far cuz it won't drive more than 5 miles without shuttin off but will idle in the driveway held at 2000 rpms for 30 min. one time i drove it and it quit and would only start if i floored it and would only run at 4000 rpms anything lower would stall but all this time is in the 40s for pressure. anything i missed? pressure regulator isn't sending fuel threw the vacuum line so i assumed thats ok but yet a week ago it started and idled fine but didn't drive it yet cuz i know what will happen

anything i missed?

We will assume fuel is fine, since you replaced the fuel pump and have adequate pressure. Check for spark when it shuts off! You could have a bad ICM or CKPS; but we can only speculate without you checking for spark.
