Leaving ignition key turned to start position makes the car hard to start

What is your question?

I have a 97 Camry, 4-cylinder LE model. The car runs well, no hesitation; if I just get in and start the car it starts fast. Like most cars, you can turn the ignition key to the acc position or the start position without starting the car. If I leave turn the car keys to the start position, and leave it in that position for a few minutes, then the car is hard to start when I fully turn the key to start the car; the ignition will cut out if I don't give it gas for 10 seconds. The engine light is not on, and there is no engine light code because of a bad bulb; I've had the engine code read at Autozone. I've replaced the ignition wires and tested the ignition coil with an ohmmeter; all is well. If I turn the key to acc, one click before start setting, just to power things while the car is not started, then there is no problem starting the car when I want to. Please let me know if anybody out there has had this problem, and what you did to fix it.
