Fuel guage not working correctly dying at idle

I ran out of gas today and my fuel gauge was reading a half tank. I thought when fuel gauges didn't read correctly it was either fuel or empty?

I added two gallons and then when to the gas station. As I pulled put the jeep in reverse to pull into my driveway the rpms dropped and the jeep stalled. What would cause this to happen?

Fuel pump. Check the ground at the parking brake. The gauge and pump share a ground and it grounds at the brake assembly

If it is by the ebrake, here is an image that might help.

The wire was actually on the other side of the bolt (nut side) but I had moved mine to the other side while testing it. The wire itself can be hard to see but once you see the bolt, you should just be able to reach your finger around the back and find it.

Thanks for the pic. A little hard to understand pic at first but prolly be easier once I feel under near my e brake. So can we clean this area of rust or just make sure contact is good. Do we disconnect the bat

To give you a bit of perspective, to the side of the bolt you can see the lever for the brake release. Also, if right when it stalls (or when it won't start back up) the fuel gauge on your dash pegs to Full, it is most likely the ground.

It's always started back up.

I found a hose with a crack. Replaced it. The problem continues. I am going to clean the iac and throttle body and replace the tps this weekend and see if that solves the problem.

You really need to check that ground.

There is not a ground by the ebrake. Could the ground be somewhere else?

There is a similar wire like picture by the dip stick. Cleaned it. It looks good. Problem is still there.

The symptoms do sound like it could be the ground. Maybe it's two completely different problems.
