My 2001 grand Cherokee Laredo shut off while driving and will crank back up sometimes right after sometimes in 45 min but it will crank back up
I had the same problem.. It eventually got worse.. I changed the CPS (crank shaft position sensor). Or you can turn the key into the on position 3x and it will give you OBD codes that can help determine what is wrong.
