Disable ignition -have helper hold key in cranking position and check for power at the small terminal black and red wire on the starter motor-don't have it check the transmission range switch and ignition switch

I tried turning the key to the run position and power is available so I pushed the brake pedal so I could put the transmission in neutral to try and start it, other than in park position and it still cuts electrical power as soon as the key is turned to the start position. It does it instantly, no lag or any other noises. It's like turning the switch shuts off all power it really seems like a relay somewhere because there's no time for a bad connection to heat up and yet it will reset to where there is power available after 10 to 15 minutes. Is there any other relays that could be causing this to happen. Thanks for your time! Dave

The ignition switch has one screw holding the electrical plug in place. Is it possible to replace the electrical portion without replacing the key portion? Because that section is riveted to a band around the steering column. I can drill out the rivets and replace them with bolts and nuts but if the electrical section can be replaced without doing so, of course I'd rather do that.

Yes, you can replace only the ignition switch.

Problem seems to indicate a bad ignition switch.

I replaced the ignition switch, just the lower half, not the entire key and tumblers, just the electrical section and it still acts exactly the same. I turn the key to the on position and the lights come on, on the dash and the dome light is on because the door is open but when I turn the key to start the starter clicks once then all power is cut, no dome light, no lights on the dash, nothing, but If you wait 20 minutes there's power available again. Is there a way to bypass the transmission selector switch and where on the transmission is it? What color wires go to the switch? Are you sure there's not another relay that could be poping besides starter relay because I replaced the starter and relay assembly already? Thanks for your help.

Recheck the battery terminals connections. I would suspect a bad connection either with the positive or negative terminals.
