Engine stalling without warning, no code set

[Rod Belmore]

I am new on here and have a problem I am hoping to get some help on. I have a '99 Grand Am Se 2.4 with about 113,000mi., and today I was leaving on a long trip, and out of the blue, it just stalled while I was on an on-ramp to the Interstate. It started right back up, and I turned around and headed home, and it stalled again, and again it started right back up. There was no check engine code set. I checked the wiring, as I did change the oil & filter the other day. I did notice however that there is a slight stumble just off idle.
I have been working on older cars all my life, but on this, with no code to go by, I am not sure where to go first. There have been suggestions about the security module, or the ignition control module.

Not much to go on. Possibiities include fuel pump, ignition switch, crankshaft position sensor. How long since you changed the fuel filter and have you ever had the throttle body cleaned?

The car was fully serviced last year, and only driven a few thousand miles, if that, as I have a company vehicle for work. I may have found something though. I was making a slow sweeping right hand turn each time it quit, and am thinking I overfilled the crankcase a little while changing the oil. I know there is a sensor in there to tell when it is low, and wondering what it does if I inadvertantly added a little too much. If that is the issue it an easy fix. However, any uncertanty would not be good, as my trip I plan to take is over 2000 miles. The car never did this before, even though we have had electrical problems in the past.

Even overfiiling a full quart doesnt cause the engine to stall. Sounds more like the fuel pump pickup. Was the car low on gas when you made those turns?

The tank was filled up, as I was preparing on a long trip. I don't think it is a fuel problem, as the car starts immediately after stalling.

Could be related to the evaporative control system since it was after fill up. If a valve stays open in the system it may have drawn in gas rather than vapor. Does the check engine light come on when you turn the key to run inorder to verify it works?

A bad fuel pressure regulator will cause the problem. Start the engine and run it for a few minutes. Shut it off and remove the vacuum hose from the regulator, if it has gas in it the regulator is bad.
