My 98 Regal GS shuts off on me. I changed the fuel filter but problem persists. Once engine is cold it will start but after about 10 minutes it shuts off and will not restart until the engine is cold. Soon as engine warms up it shuts down so problem seems to be temp related even though temp gage is in normal range & oil lite does not come on.
Ok its one of two things you need to check when it cuts off if you have spark or fuel if you lose fuel pressure replace pump it gets hot and makes noise like its running but its not pumping fuel and if you lose spark you need to replace ignition control module has a hair line crack in it and when gets hot the crack expands and loses contact and wala no spark
ok so when it wont start we still have fuel pressure and sparkwhile its hot try taking a scanner and check the coolant tem sensor and see if it is reading the same temp as car if it difers more than 10 degrees replace cts try that and let me know well figure it out to bad you wernt in ga i could come look at it

As suggested, I checked fuel pressure with a gage and do not lose pressure until after the engine quits and will not restart until it cools back down. Removed ignition control module and it passed all tests repeatedly. Any other advice will be appreciated.
