I had the problem last summer and fall when the temp was about 70 or above. Didn't drive it for a month or so and replaced the fuel pump relay and injector relays. Drove all winter with 0 problems. The second the weather hits low to mid 70s again...can with drive about 30-40 minutes and just dies. I have to turn the key to off...give it a second...and it will start back up.... the longer I keep it off, the further it will let me go before it dies agin. Yes it throws codes...but it is hella codes from it dying while in motion. I noticed last week that the fuel level was going crazy when it was dying giving me weird fluctuations from half a tank to full tank (it was full). So I replaced the whole dang fuel pump assembly. $260 later and it is still doing it.....I've done a ton of research and can't put a finger on what this could be. Any suggestions would be great.

 

Read up on the faulty electrical connections inside the ignition switch as your problem. I think there was a bad batch of them in your model year and possibly a TSB on it.

 

Yea, I have seen a lot of info on the ignition switch being a recall. The test for that is to wiggle the heck outta the key when it is running to see if it dies....mine stays running with aggressive wiggling. I don't see how the warm weather would affect that issue, though.

 

Pop the plastic cover off the the top of the steering column and wiggle the big connector on top of the column.

Also, please list every specific code. We may be able to figure something out from those.
