Manual IS loses electrical and dies with clutch

What it going on with my 02 manual IS300? In the last week I Have lost electrical 3 times. Each when I time when I pressed the clutch. Twice in parking lots traveling 5mph, and once shifting 2nd - 3rd at about 40mph. Each time it was only long enough to reboot my stereo but this morning on the way to work it actually died in the road as I was shifting to 1st entering the parking garage at work. All electrical was out, headlights, dash lights, everything. And it all came back as soon as I let the clutch out. I had to restart and it started like normal so I was able to get out of the road but what is going on???

I’ve checked the battery terminals and they are clean and tight. I looked up under the dash and there are no stray wires over or near the clutch pedal. Could the clutch/start switch somehow be causing this??

I doubt it's the clutch starter switch on the pedal wiring, that would cause intermittent starting issues not what you're describing.

This issue sounds more like a dying battery or alternator. I would take it to an auto parts place that does free charging system tests to determine the problem.
