On longer trips (greater than an hour drive), and seemingly worse on hot days, my car has been pretty consistently getting into a state where it stalls when I stop at a red light. It takes a few tries, but it eventually starts afterward.
None of the check engine, voltage, or temperature lights have come on prior to any of these events.
I noticed if I give it gas, or pulse the break in a certain way I can sometimes keep it from stalling out.
I had it in the shop to check the idle air intake, and they said it was clean. Also they were unable to reproduce the issue in the shop, though it has been happening on most stops after a certain point on a long trip.
