Fuel Injection and O2 sensor Codes - Stall 700

I know this is the 700 series forum and my car is not, but I have not got any response on that forum and figured some of you guys may have had similar issues on 740's? Thought I'd give this a shot..:)

----------------------
A couple of days ago my wife was driving the -93 960 Wagon when it suddenly "died" while driving on a street maybe 30mph. She called me and I was lucky to be close by and went to check things out. The engine had just quit with no warning and displayed CHECK ENGINE light.
By the time I got there probably 15 mins, it started up just fine again and drove home with problems.

There were two (only) codes present: 113 and 115 Injector group 1 and 2 acc to the book.

I have seen a couple of posts here with similar issues, and ideas that it may be loose or poor ground connections somewhere around injectors - but nothing conclusive as to reasons (as far as I could find).

I cleared the codes and car ran fine for two days and then again yesterday the CHECK ENGINE light came on, this time no stall - the car contuned to drive normally acc to the wife (not running rough or anything).

I pulled codes again this am, and this time only one code present: 212
acc to book HO2S signal, (Something wrong with 02 sensor...)


Any ideas what is going on with the car?
Could it be an Oxygen sensor that is on it's way to give up? Or just bad connection by one of the O2 sensors? But then again, not sure why that would cause the first codes 113 and 115 and not O2 code the first time around...

Any suggestions on how further trouble shoot to fix the issue(s) would be greatly appreciated - the wife is a bit nervous driving it and get stranded..
Thanks!
