Long time lurker here. This has been a great resource for all my past problems, but I've got a problem I haven't been able to diagnose with existing resources.
The Problem: was driving the other day, came to a stop. Made a gentle right turn, and the car just dies. Tach drops to zero, fortunately I'm able to get the car off the road and towed home. A few hours later I start it back up, no problem, it idles fine. It'll run for a few minutes, until it reaches approximately operating temperature, then it'll start to misfire, the tach jumps from about 500-1500rpm, and then dies. If I try to restart it immediately the starter will spin but the engine won't catch. I can't get it to run again til cool.
The Condition: ~160k miles 4g63t GS-T Spyder, brand new timing belt and water pump. Ran the car 150+ miles before this problem so I don't think either are related (PS the forums and FAQs here were instrumental in getting that done
.) Though, I did noticed the new water pump was an "induction" design, if that's the right word. Pulled the throttle body the other day to clean, but it was already surprisingly clean, noticed the intake manifold was dirty but not much I could do about it, and put everything back together. NGK sparks as old as the belt, brand new (still lousy) Bosch 7mm spark wires. Also, when putting on the new cover I noticed the CAS plate was worn shiny on one edge, I think it'd been scraping the hydraulic tensioner.
Things I'm going to be checking: TPS, ignition coils. What else?
Does this sound familiar to anyone? Any help would be much appreciated. I'll try to upload some pictures and videos tomorrow.

Oh well. The only thing that looked unusual to me was the O2 1 Bank 1 value bouncing around between ~.1 and .7
