I have a 2001 Nissan Altima and mine did the same thing. We replaced the intake gasket. It costs around $5.50, but it requires several different kinds of tools. We spent over $100 in special sockets, etc. But once you replace that gasket, it will idle better.

Got the same make/model/year, but haven't had that problem. Does your temperature gauge run at half or above when this happens? If so, start with a cheap fix - new thermostat.

Another thing to consider is that some of the QR25DE engines equipped in the 02 Sentra SERs has an active recall on the crank position sensor. This fault would cause the check engine light to come on and the car would stall unexpectedly. It should start back up but the frequency of this will only increase without repair.

Also, no need to change plug wires, you have coil pack ignition - there is no distributor. If a coil pack is bad, you will have constant misfire and SES light.
