Sounds like the ignition switch solenoid problem. It's a harness connector from the ignition switch to the main harness.

Give it some time, to make sure. It can throw the tranny into limp home mode / 3rd gear only. If it does that, you can re-set the computer and clear the history.

Costs about $70 - $80, under 2 hours to change.

Make sure first...
