For those who have been following this thread and may have similar problem. I ended up putting octane booster in the gas (routine for me) and the car still stalled, but did not die. I also ended up putting premium instead of mid-grade in this time, so I'm sure the combo had a big thing to do with it helping out.
I'm going to see if this will make any difference in a longer term and post my results back at a later time.
If this doesn't help your situation, revert back to previous suggestions.
Thanks!
