Hello IrmoDog and welcome to our site! 
I'm pretty much in agreement with CW but would like to add, check your fuel line connections to the pickup very well. We had a CJ that had a pin hole in the fuel line at the tank. It would only run well when there was a full tank of fuel. The pump could over come the bleeding of air when the tank was full but when the level dropped it sucked more air.

Are you sure the gauge is working and you are not running out of gas when the gauge says 1/2.?

I have filled it up, then ran it until I get the "cutting out" and then refilled and it will hold about 3-5 gallons at most.

Yep - sounds like a pick-up tube...

Had one doing the same and it was trash in the tank.
Doubled up on the fuel filters, 1 before pump and 1 before carb.
Problem fixed, but had to change filters a couple times.
