5.0 gxi e trouble

Replaced long block dew to piston 6 blowing up. Re dressed motor with existing intake fuel injection hoses etc. new items include iac, crank sensor , cam sensor , plugs wires cap and rotor , serpentine belt starter water pump impeller. Motor ran good in drive way with hose hooked up. First water trial was terrible. Starts great idles ok for 5 min or so then sucks air and quits. Ran rpm up to 1900 same result sucks air and quits. Any advice pls.
