95F+ degree weather when I'm at a complete stop give the car a little gas my engine stalls. I believe all electrical is still functioning, I start engine again hit the gas and go.

Same conditions 95F+ outside at a complete stop, if I give it a little gas it seems like car is going to stall. It's been doing this even when my car had 20K miles so since very beginning just think I need to take care of this issue now.

Any help or what to replace would be appreciated.

 

That problem was there when the car had 20K miles. Now, car probably has more than 100K miles. What prompted you to take care of that problem now?

 

I'm going to Vegas in a few weeks going to be 100+ so it's a good time to test. It seems to happen when car has been subject to 95F+ temperatures for 3+ hours or so... I'm sure this trip it will happen 2 or 3 times entire trip.

 

If its been like this for 80,000 miles I don't think its a big issue. Are there any codes thrown?

 

No errors with INPA. I have OBDII adapter in my glove box just in case it throws error I can read right away with iPhone BMWhat app.

I hear a lot about people cleaning MAF, replacing HPFP, replace pre & post O2 sensors etc... my Indy shop wanted to replace some part where you hit the gas pedal it delivers fuel to the engine. Not sure what exactly he was talking about have to ask him again.
