2000 Dodge Caravan Engine Dies; Will Not Restart

Engine Performance problem
2000 Dodge Caravan 6 cyl All Wheel Drive Automatic

I have a 2000 Dodge Grand Caravan with about 90,000 miles.

Was driving on H-1 in Honolulu, HI, when the engine suddenly stopped completely. Dash lights flashed, but then returned to normal. Turned key; nothing; no click no starter. After few minutes, turned key, starter turned over but engine did not start. Called tow truck, which hooked up van and drove to service center about four miles away. After the van was unhooked, I tried the engine again, and it started right away, and I drove it home about five miles with no further incident.

What advice do you have re the potential problem(s)? Gas line; electrical system; computer?

Thanks.
