That should only happen when you are low on gas, the fuel pump is getting deprived of gas and is stalling out the engine.

Truthfully, from your descriptions, it could have a few possible causes. I usually like to recommend the least expensive possible causes first. You know, the ones that just take some time and diagnosis? Then, move on to possible bad parts issues and the testing required to determine them.

So, that having been said, do a few of these checks first and report back. Then we can go further from there if necessary.

1) Pull the battery connection covers back and carefully look at both the positive and negative cable ends. Is there any corrosion on the connectors? The battery posts? The cables themselves, under the wire covers? If so, remove them and clean them up well and apply dielectric grease before re-assembling.

2) Follow your cables to their engine and fuse relay connections and review the connectors, posts, and wire conditions there. Clean as necessary.

3) Have you ever replaced your fuel filter? If not, or if not within 15,000-20,000 miles, do so.

4) Observe more carefully the conditions when it cuts out around corners. Is it just when you have 1/4 tank of gas or less? Detailed information will make it easier for us to try and help.

Report your findings back here.

OMG... How could I miss this.

Dyno.. You have the EXACT and yes, EXACT issue I have been dealing with. After trying tons of stuff with only success in making it happen less often (so far) I'm here for you.

Ok, first things first. Read that thread on P0171 that Lash has linked above. Battery connections seem to be the largest factoring item so far.

Do get into the car and clean all the contact points for grounds and positive cables. Also MAKE SURE to remove the plastic boots covering the battery cables at the battery to look at the connections.

My issue started when I changed the battery.

Was there anything you did regarding electrical system? Starter or anything like that?
