Dont think this was brought up as of yet, if so i apologize for the repost. Anyway i used to have the stall issue with my jwt popcharger, everytime i put it in neutral when coming to a stop at high speeds my car would stall.

Fix-I cleaned my MAF and Throttle body and my car doesnt stall anymore. I tried numerous times to get it to stall like before and nothing. Hope this helps anyone with this problem (my throttle body was extremely dirty btw)

 

Yes. The solution is not to put the car in neutral before stopping.

 

Just for the "piece of mind" i guess, worth a shot if your having this problem

 

I tested this out and put the car in neutral at various speeds. Never stalled once or got even close to stalling. I don't reccommend putting it in neutral anyway because you have more control slowing down while in gear. Probably like the OP said, dirty MAF.
