Are you using the CORRECT plugs for the car, or something else? Should be using just the normal Bosch "Super" plugs, non-resistor plugs. The platinum tipped or split-fire or other fancy plugs don't work as well as the regular ol copper core Bosch plugs.
Also you could pull the plugs to check for deposits, possibly could be valve stem seals, or at 300,000 miles could need valve guides.

I am running bosch super and only use premium fuel. I have checked the plugs and they look really good. I had the valves worked over about 60000 miles ago. Like I said the car runs fine once cranked. It is just so hard to start after stopping to run errands. Could it possibly be the injectors need replacing?
