Experiencing a similar issue right now, the car also sat for 3 days or so and 2 weeks ago I changed the ground strap to the battery. I am almost sure these facts aren't related, but since you mentioned removing something from the battery, I though I'd mention it.

I was experiencing an issue where the radio would lose power intermittently, as described in this thread. I changed my DME relay, made sure my wiring harness recall was performed and cleaned and eventually replaced the battery's ground strap. The last action appeared like the solution as my radio has not been acting up since. Two weeks later and the whole car dies when "pressing" the clutch (twice on a 30 minute run through the city).

Note that I suspect moisture as the culprit, we had some intense rain here.

My 96' doesn't have the interlock if you mean the clutch peddle needs to be held down for the starter to engage.
I would think a faulty interlock would influence starting, not running though.

IXLR8

Neither would a DME or anything else at that particular time when the clutch is released.

I still suspect an aftermarket anti-theft system.

I just checked my schematics to see what that clutch pedal switch is connected to. Not a logic relay or anything else other than cruise control.

Railmaster.

ROW 993s does not have this odd feature!

Similar issue happened to me this morning. Changed out the interstate battery last night. Tried to use trickle charger to not lose the idle stabilization algorithm. While the radio reset, it seemed the car was idling fine. Drove start/stop for 10 minutes to interstate. 25 minutes on interstate. No issues even with getting off interstate. Wasn't until pulling into parking lot that it decided to stall every time the clutch was depressed. Coasted into a parking spot and checked with an awesome mechanic in Dayton area (Yuri), who said its the idle optimization algorithm. His recommendation is to start the car, let it idle for a few minutes. Shut it off. Rinse, repeat until the idle revs high then settles back down close to 1K. Should be good to go after that. Will do this later and report back. These cars are tempermental. Kinda like an Italian woman??? Definitely not teutonic from that stand point.

I used to get this after the LWF install. Isv cleaned no different but since I convered to Vram it hasn't stalled. I used a '96 RoW Vram ecu. Idle was very lumpy on first start up but after 3mins 20seconds of idle it all settled down.

Will it idle in neutral with the clutch pedal up or is it stalling in gear when the engine starts to see a load?
If the latter, that sounds a lot llike mine did with a bad (and wet) cap and rotor for whatever that's worth. Weak spark or something.

Again in all these cases if its stalling after you disconnected the battery, did you let the car idle for 10 minutes when you reconnected the battery to let the car relearn idle. If not, then worth trying.
