My 2002 Honda Odyessy engine stalls while driving

What is your question?

While I am driving my Odyssey (2002) my engine stalls completely stops running, and loses all power. I am able to coast to a stop. I am not able to restart immediately, but after 3-5 minutes the van will start. It is as if there is no gas. But it never sputters. After 3-5 minutes I am able to drive the van without any problem. The problem is intermittent, have had it in the shop, but of course it does not repeat for the technician. Also there are not codes either.
