Hi - I have a 2005 Grand Cherokee with 5.7. It stalls when I plug in OBD2 Reader. When it stalls it also resets my IM readiness monitors. Very strange. I am using an Innova 3160 OBD2 reader. Has anyone else encountered this? Any insights would be very appreciated.

You aren't supposed to plug it in when the vehicle is already running. You're lucky you haven't fried anything yet. The ignition is supposed to be OFF before you plug it in. I strongly suggest you read the manual for that thing before you do some real damage.
