This has historically manifested itself (at one time or another) as a symptom in one member's truck or another. The top, windows, rear deck lid, power locks, cruise control, lighting systems, radio, A/C, transmission, and a crap load of others...... the most obvious has been the instrument cluster.... You have no idea where the gremlins will attack.

Go get a can of Raid and kill the bugs that run out of your system when you replace the ignition switch.

OK boys.... Can I have an AMEN????

AMEN

Dave,
Welcome to the group. As you find your way throught the site you will soon learn that there are some names that garner great respect and others who provide for the comedic relief. You have met two of the heavy weights in the respect category. Mike in AZ as an engineer who has provided many of us with equipment that outperforms the OEM parts, and Greg who is one of, if not the main, voices in the world of transmissions here. The rest of us will most likely agree with the comments about the ignition switch module.
