Sounds like your fuel inj. pump might be worn. Mine was doing that after it sat a 1/2 hour or so and the engine was too warm for the glow plugs to light. I ended up replacing my fuel inj. pump and the problem went away. You may want to try a manual switch on your glow plugs but be real careful you don't heat them too long and burn them out. I never got around to putting in a manual glow plug switch.
You should have two starting batteries. When I got my motorhome a class C, I was missing the battery under the cab. I also have two coach batteries.
