08 GC 5.7 Shuts Off at 40MPH

Hey guys and gals

I have had my Jeep for about 2 years. Early on it shut off on me about 3-4 times while i was sitting idle at a light. Didn't think too much of it

The other day, I'm cruising around 40 mph and go to switch lanes to pass a car. Push on the throttle aggressively and the car shuts off on me. Had to cruise to a stop, then I was able to start it back up no problem. No engine/error codes after the incident.

Now i am a little concerned, any thoughts??

Last time something like that happened to me, my fuel pump was starting to go bad. It didn't go all bad at first, just cut out sometimes.

Re: Car shuts off at 40MPH

Did you check if any fault code is set? Don't know if key dance works on WK: ignition switch off/run three times and leave in run at third time. Odometer shows Done or fault code(s).
Expect a crank or cam sensor, but fuel pump is eventually possible as well.
