Fuel Frustrations and other things.

My jeep has started to behave as though it is running out of gas. It does the sputtering and such. It cut off on me twice today coming home from work, even. It has never done this before, and I am very confident it has gas, as I had just put some in it. If it matters, it has a V8 Magnum motor in it.
Any thoughts?

Also, my rear wipers used to work, and suddenly they don't. I changed the fuse, and they still didn't work. The plug for charging accessories doesn't work either, and changing that fuse didn't help.

Any thoughts, here?

Thanks again everyone.

Fuel filter changed lately. Visual inspection on the fuel lines is in order. Fuel pump internal or external. Then are you running a carb or fuel injection?

The fuel pump is less than four months old, I haven't changed the fuel filter in quite a long time. I was thinking the fuel lines yesterday, but today I found that a vacuum line had broken. I patched the separation with a piece of rubber hose. It then rode like new for about an hour. Then the issue started up again. I checked the patch; still good. It is fuel injected. I can't even keep it running now. Acts like it has almost no gas.

It was an unseen vacuum line. I fixed it. Runs great. Or at least it did. Now it has having a similar issue which I suspect is related to the spark plugs. My engine is using Bosch Iridium Fusion Spark Plugs. Part number 4501. Gonna swap those out and go from there.

Get the cheap stock copper plugs. For some reason the engine likes those cheap plugs and doesn't like the expensive new ones.

Should I stick with the four grounded one or will any do? Also, there seems to be another leak in the vacuum line, one that isnt evident on any of the lines I can see to asses. I know I heard the leak but I cannot find it. I cant afford a smoke machine, and will probably make one, just to check. The symptoms are exactly the same for the vacuum lines I have fixed before. Is there anywhere else I should look apart from the vacuum lines? The intake perhaps? I don't even know.
