After the engine turns off, do your power windows work? I'm having a similar issue on my 91 accord where the engine shuts off after starting it. I believe the ignition switch is faulty since the additional items are being observed:
1. Turning ignition from Running to Start and returning to Running shuts down engine. All accessories and power windows have no power.
2. Turning ignition from Running to Start and returning the key close to the Running position leave the engine running.
I believe internal contacts of the ignition switch are worn down.
