Good idea to set the idle speed (donissan) but you can't do that if the slow-run jet is blocked or dirty. Remove the jet, clean it thoroughtly and before replacing it drain the reamaining fules from the carburreter and clean it out!!
This is not an easy one to diagnose. I am working on one that does the same thing. I have done a lot of research and this is what I found.
First try seting the idle speed.
If it still stalls it could be the mass air flow sensor. or sometimes it is one or more ignition coils.
The easiest way is not the cheapest, but it is to change one at a time . start with the rear coils first.

i have the exact same car. And after a lot of searching, found the EXACT cause for this. Its your TCC switch (torque converter clutch switch). It has somethign to do with your transmission, and kicking the car into overdrive at certain speeds for fuel economy. Anyway, mine would stall out after driving for more than 15- 20 minutes, especially at highway speeds, which when you think about it - is the speed if you had a manual/stick - you would be shifting into the highest gear. Well, this chip or whatever it is basically gets "stuck" in high gear. And when you come to a stop, its like trying to get going in 4th gear on a manual from a dead stop. NOT happening!
I checked with a few people and did some searchign online - and found out all you have to do is unplug the wire leading into your transmission (not a car guy so I'm not sure exactlyif that's what its plugged to, but on mine ,same model and year as yours, it was blue on the very front on the engine way down dead center almost if you're standing in the front of the car looking down). I believe it was a 4pin connector when you unplug it, but I'd have to go doublecheck. NOthing at all bad happens from donig this - all it does is you lose about 3-5 mpg when you drive. I still get 25-27 mpg. If your car isn't in awesome codition and you dont want the headache of some mechanic taking everything apart to get inside the transmission to replace a dumb chip that just kicks your car into overdrive, I'd go this route. Worked for me.
I have checked all over online - and everyone who had this problem and unplugged it, had no problems ever. NO side effects. One guy says he's run up 100,000 miles since then and still runs like a top! If you need more info or whatever - email me. I dont mind. I'd love to know I'm helping someone out so they dont have to deal with it as long as I did! [email protected]
