The glow plugs don't cycle when the engine is near operating temperature 
and the problem is that the starter doesn't spin the engine fast enough 
when it is near operating temperature for the engine to eventually fire. 
The more times it turns over, the slower the engine turns. I don't think 
a relay will work unless it makes the glow plugs cycle every time before 
turning the key to the start position.
"Hot" does mean at or near operating temperature. The starter doesn't 
sound like it is slower until the engine has turned over a couple of 
times. When the glow plugs cycle, the engine doesn't turn over once 
before it starts. Maybe a half a turn.
