Hi everybody...

Had an experience on the way home last evening that got me a bit "concerned" while driving my 2002 9-5 Aero (I commute 65mi each way)...but I think I have an idea as to what might have happened - so hoping someone here might be able to validate my thought process, or tell me if I'm dreaming and I really screwed up the car.

Here's the deal...on my way home, which is about 10mi away; nearest gas station is roughly the same. Fuel is low; low fuel indicator is on, DTE reads 13 miles left. So I figure, ok, I can baby it back. Been driving conservatively, minding my mpg's - cruise control is set at about 60. I begin a gradual slope uphill toward the final leg of my trip - and upon hitting the incline (gradual incline to start) I can feel the cruise starting to slip a bit - DTE is around 9 - the car actually sputters - flashing CEL - car begins to lose power, no real juice from the gas pedal.

I assume this was limp home mode. But - there was no message on the SID, and no red "!" triangle of doom. I pulled the car over to where it kind of came to rest (now pretty flat), and turned it off. Took the key out, waited 5 seconds, put the key back in and started it up - right away without issue. No lights on the dash, no nothing - all was well. Gave up on the gas strategy and drove it normally to the gas station and put 10 bucks in til payday.

So using what little technical knowledge I have, I'm wondering if this was the chain if events that might have occurred:
*driving, low on fuel and using cruise control...
*upon hitting the incline with so little gas left, the fuel pickup sent less than a 100% supply of fuel to the engine...
*the throttle body, recognizing this fuel supply issue/shortage says "hey wait"...and throws limp home mode...
*restarting the car (which was on flat ground) has allowed full supply of fuel back to the throttle body - which has cleared LHM for some reason (for now, at least)...
*putting a couple of gallons of gas back in has alleviated this problem...

Does this sound like a reasonable explanation - or am I hoping for something too simple, and I really jerked up the car (like the cat, throttle, etc)? Any/all guidance welcome - thanks in advance!

Unfortunately that does not add up. When the car goes into limp home mode you have to physically reset it. Also it will throw two codes, turn off your cruise control, and turn off your TCS.

And that's the thing that got me too - no codes!
Any other possible explanations as to what might have happened here?
Was this just a "low fuel freakout"?
Not crazy about getting back on the horse tomorrow - esp since there's no code to give to a tech and say "this is what happened."

Anyone? Thoughts?

I'd have to agree with Polluted. If you are worried about it just let it idle in the driveway tomorrow for ten or fifteen minutes.

Thanks guys - took the advice, also topped up the fuel tank and made my drive to work. Zero issues (thus far).
