Many times a "no start when hot" condition is due to bad Injection Presure Regulator (IPR) o-rings. The bad o-ring will bypass the thinner hot oil causing a no-start. If there is not enough High Pressure Oil System pressure, the injectors will not be commanded to inject fuel. The IPR O-ring kit is cheap, so it's a good place to start.
