Be sure and a get a real mopar sensor.

 

Welp,

Apparently the mobile mechanic was right. I replaced my crank sensor and now she no longer dies at stop signs. I clearly have a rear main seal leaking based on the oil film that was covering the old sensor.

I will report back if the problem returns, but for the time being it looks like we're in the clear!

Thanks for everyone's help and I hope that someone finds this thread useful!
