Loss of power from sharp turning can feel like a stalling,chances are your belts may be worn or slipping or not tensioned properly,check for any oil on them also.Sharp turns place a lot of pressure on these.
i have been battling the same problem for 5 years in my geo, it seems to have gotten worse as time passes. full tank and make a sharp left, hard left, or high 'G' left and the engine sputters, chokes, or dies. when i had my wide band sensor in it was loosing fuel, it was not a wiring issue as i had constant voltage at the fuel pump, fuel filter was changed, pump was changed, inlet filter was changed several times, tank was checked for debris several times, etc. i could never figure it out and it had gotten to the point where pulling out into traffic was dangerous.
Those sort of troubles are idle control issues. Its supposed to keep the idle up when encountering a high load, like hard steering and AC compressor going in and out.

As you found out its NOT a fuel issue.

thats not my issue though, foot is on accelerator and engine cuts out and wideband goes totally lean. I AM loosing fuel, he could be having a different issue.
Yeah I had a feeling it might be an idle issue. I also have a problem where the car idles pretty high on cold starts, about 1500rpm.
On cold starts quite a bit of fuel is condensing on the cold walls of the intake. ECU will compensate and add fuel as well as it will open the idle air control valve, making the idle higher. 1500rpm is not abnormal. It should go down after a couple of minutes though.
1500rpm is definitely abnormal. It shouldn't be that high unless it's winter and even then it's not normally that high.
I'm sure there's an idle air control valve that might need adjustment, or whatever Toyota decided to call it.

No that's definitely the issue I'm having. I even tried it at WOT and the engine stills cuts out. I haven't done any testing to check it out yet though.
Haha please explain to me which magical belt you're speaking of?
Hey I'm just trying to help.I had a similar problem when I'd go to park at work ,I'd always have to take this really sharp turn and my car would lose power and start to buck like it's stalling ,once the wheel was corrected it returned to normal.I talked to my mechanic who said I should have my drive belts checked or maybe my alternator was dying.The belts were pretty worn so I replaced them, and guess what ..those magical belts stopped my vehicle from dying on sharp turns.My mechanic explained that the engine needs to do more work to assist in the power steering,which will draw power from the alternator.If the alternator cant handle it you'll lose power,if the alternators good, the belts may not be properly tensioned or slipping.My car never fully died but it felt like stalling,which had nothing to do with a fuel problem.

my belts are good, alt belt is new and tensioned well and alt is working well, but i will double check those things when i see the car again. gotta fix the trans.

No, the alternator has nothing to do with your power steering pump. Your power steering is all mechanical and hydraulic. You may have a sensor to tell the power steering pump what speed the car is currently at, but this only has an effect on how much pressure the pump sends to the steering system; it's called comfort-assist power steering, it basically makes the pump send less pressure when the car is traveling at higher speeds to give the feeling of more 'direct' driving. Even if the alternator wasn't turning at all or your main alternator fuse was blown, it would still have absolutely no effect on your power steering so long as the engine was turning. Your engine would have to bump up the idle maybe 100 RPM higher to make enough power to turn the pump, but if an extra 100 RPM was causing alternator problems for you then your car would be stalling as soon as you put it in gear.
I do not think new accessory belts actually solved your problem. To me, this is just a big coincidence. You replaced the belts, and at the same time, the problem just happened to go away on it's own. I strongly advise you to get a second opinion on some of your mechanic's ideas as well; in my eyes, he's lying to you. Because honestly, stalling being caused by the accessory belts is about the most ridiculous thing I've ever heard.
