if it is starting ok cold dont think your glow plugs are at fault,have you checked the tank cap?remove it and see if there is a hiss,you may have a vacuum in your tank

might sound silly, have you checked the air filter. quick check, just take it out. If it runs, get a new one, Dont run for any time without it.
If not that, I would look at the glow plugs, might be breaking down when hot.
