Intermittent stalling

Hello and Merry Christmas: I had asked you a question a year or so ago about a 2011 Dodge Grand Caravan one of my daughters has and your email advice at that time was very cordial and helpful. Thanks again for that.
Now I have something to run by you on the vehicle listed above another daughter just bought a few weeks ago. Twice now it has simply quit suddenly and unexpectedly in heavy traffic, needing to be pushed off the road by passersby. Unsafe and unnerving, to say the least. After waiting a bit, the vehicle started again and went on its merry way.
Have you had enough experience with such vehicles to know where one might look? No engine codes or pending codes show on my simple Autel OBDII reader. Looking up on the web, I see that forums show that issues like this could arise from faulty coils, ignition modules, fuel pumps, ignition switches or main relays. A recall (No. 02V120000) was published in 2002 by Honda for a variety of vehicles of that vintage to replace the ignition switch because the bulletin said that failure could cause a crash.
I recognize that intermittent problems of an electrical nature are hard to diagnose but appealing to mechanics who have years of experience, of course, is a great place to start. I may have to go through the process of replacing a few parts to eliminate the most likely or least costly possibilities. Thanks! John.
