But after it has run for 5 or 10 minutes and then stopped for a minute or more, it becomes hard to start and idles rough for 30 seconds and then it is OK.
I have changed the injectors, fuel filter, plugs and wires. Not sure where to go from here.

When was your last oil change, and how many miles are on the engine? You may want to try adding one of those oil treatments for worn engines.
