Car stopped mid drive. 2003 with 113,000 miles. Ignition cranked well and all gauges fine, but engine would not turn over. After about 10 minutes wait, engine started up again and car runs fine. Don't want this to happen again. Fuel Pump issue? Other? Thoughts? Thanks!

Car Just Stopped Running. Issue?

Could be a fuel pump problem or a lot of other stuff. Absent more details there are a number of things that could cause this.
If the main EFI relay is original I would check there first. A main EFI relay failure is characterized by the CEL failing to illuminate when the key is turned to the run position and / or the fuel pump failing to go through its prime cycle (although a dead pump and a dead ignition switch will also do this). The main relay is also noted for intermittent failures - just whacking it may cause it to resume temporary operation. On an un-modified car I would bet a whole beer that the main EFI relay will fail before the OEM fuel pump.
The failures on the main relay are normally due to solder cracking / migration. Details here

If you are handy with a soldering iron you can usually restore the relay to just about new condition. So, examine the relay for cracks and if you can solder do the repairs. This is a cheap and easy way to test. If it fixes the problem, purchase a new relay and install it and keep the repair as a spare for when the relay fails again in 20 years.

Another main EFI relay failure data point
Another data point for the list of main EFI relay failures - 2000 model year with approximately 76,000 miles. I had almost convinced myself that the main relay failure was an early model 'thing' that had been fixed during later production years and that it would not be an issue for me...

Cranking = Engine turning over
So I think you mean the engine is turning over but not firing up.
Next time tap rear bulkhead above the center speaker a hand width below the glass.
If that fires the engine: main relay.

Do you hear the fuel pump priming when you turn the key on? Are you on a stock ECU?
