Ok folks here's my problem I have intermittent hot water? I hear it fill, I hear the D.I ignition fire when it's needed and turn of as I I think it should, when I turn the hot water on it gets warm for a few seconds then back to cold, oddly enough I can even get the same Symptoms out of the cold line ??? No clue! There is a mess of valves I think I have everything in the open positions but still stumped can anyone help?

If all the valves are open , that is your problem !
At the rear of the hot water tank , if you have 3 valves , the top & bottom ones should be open and the one in between should be closed.
This is a winterizing kit ; if and when you install RV anti-freeze; you close the top and bottom valves and open the center one , and drain the H/W heater at an out side drain. This is so you can pump RV anti-freeze through all the pipes ( about 2 gals ) and not fill the tank , that would take 6 gals more.
If you have an outside shower , make sure the taps are off there , not just the flow valve on the shower head.

Skip is right on: I'd add, check to make sure the faucets on your INSIDE shower are turned off as well.

Ok all the valves are in the right sequence, the winterizing valve is closed and it's still doing the same thing do you think I could have a hydro lock?

Not sure what you mean by hydro lock. Air pocket

But if getting the valves in the correct position didn't get you going then we're back to square one.
How long does the burner run when it lights up ? 6 gal tank should take 10>12 mins. to come up to temp from cold.
When you say hear it fill , are you filling the tank with a hot water tap in the coach open and bleeding out all the air? This should take 3>4 mins. hooked to city water, if the tank is empty , and 6mins if filling with the pump from the fresh tank.
Can you post a picture of your valves on the tank ?

I have never filled with the faucet open but will empty the tank and try again with it open, yes firing time is quite normal and fill time is too, ill try that tonight and will let you know!

I had the exact same problem on my rig. Check then re-check your winterizing valves. I'd bet a box of donuts you have something closed that should be open of vice versa.
