I start my car and let it fully warm up. Then I shut it off and let it sit for about 30 mins and when I go and start it back up the engine stumbles and then regains power, sometimes it shuts off completely :( . What could the problem be in this situation :?: Thanks.

1999 Saab 9-5

Here are the various things that could be causing this problem...
fuel filter (replace at 60k)
dirty throttle body (clean every 25k or so...these are known to fail frequently after 60k miles. Im not sure if cleaning will improve longevity or not)
crankshaft position sensor (not too familiar with this one...just heard it blamed numerous times)
spark plugs (check for fouling, regap, replace if necessary)
Hope this helps...

Fixed!!!! Brought to the car to my Saab Specialist mechanic, not the dealer (they over charge) got the throttle body cleaned out, replaced the spark plugs, cleaned out the intake pipes and its running much better!! Thanks for the help :D
