No start when hot

[stmitchell04]

Have had the truck at two different shops so far and no luck. Replaced hp pump and dummy plugs as well as a few fittings and orings, also replaced FICM still same problems. After running for 15-20 minutes truck will just die, and will not turn over at all till it cools down about 10-15 minutes as well it kills power to the fuel pump. Any ideas would help 2006 F-350 SW

Well if it runs out of fuel it will certainly quit running. Sound like a bad pump or relay,anti tipover switch, neutral safety switch any of those.
