Truck just shuts off

It has done it a few times now. I start my truck up and about 30sec it cuts off, I try to start it and it just spins over. I pop the hood and prime the pump a few pumps and try again and its starts??? LBZ 2007 44k miles on it. Going to change fuel filter and if it happens again will take it in for warranty work.

have you checked your bleed screw to see if its cracked? or a cracked fuel line letting air in the fuel system? change your filter as you planned

I agree, First thing make sure the fuel filter has been replaced in the past 12,000 miles. Then the Bleeder screw is one of the most common problem spots that will cause that.
If thatís the case we offer an Aluminum one to replace the stock one at the below link:
If that doesnít fix it, spray down the filter head with brake cleaner, make sure itís all clean and dry, then pump the primer until itís good and firm. Look around the wires on the filter housing, and such for leaks. Otherwise thereís some other leak on the low pressure side of the cp3 pump ( between the pump and tank). So look for moisture/heavy dirt to show signs of a leak.
