Need some help with an intermittent stalling problem with my 2002 Overland. Every now and then when I put it in reverse and back up, it stalls.This happened 2 times already. The rpms would kinda flutter and drop till it dies. I then put it back in park and it starts up no problem. Anyone have any ideas what could be causing this? Electrical problem? I'm thinking fuel filter possibly, air filter, or iac? Any help would be appreciated thanks!

My Overland stalled while idling a few days ago but started back up without any problems. It hasn't stalled ever since. So I'm wondering what could be the cause. Any suggestions out there?
