Car only starts when cold. Would heat cause Crankcase position sensor to fail and not send fuel until it cools off??
I just had new sensor installed …..then car only starts when cold not when warmed up. Could the new sensor have been installed
incorrectly or did I get a defective new sensor????

Have the fuel system air and temperature sensors been checked, more likely one of these.

Assuming the 6 litre is same as the 5.3 both sensors on L/H bank, coolant sensor nearby to thermostat and air sensor on air cleaner inlet trumpet. I am not sure what the resistant values of these are meant to be. At least on 5.3 motors it is possible to mix the plugs up.
Doug just started a thread regarding coolant sensor may be helpful to you.

Was this the front sensor? Yes if its not functioning right it may start cold but die on warmup or otherwise fail to start while warm/hot. Did you install it yourself? Theres supposed to be a specific gap between the sensir if Im not mistaken.
I had the same issue 3 yrs ago, new sensor fixed this.
