Um, Hey jr,
I think I may have stumbled onto the cause of your problem. I see you have a mixing valve in the shower. And I suppose you have hot and cold water at that valve? So you turn on both knobs like a normal person to get warm water correct?
If so, then Bingo! That would drive the EcoTemp batsh*t crazy! It is designed to be used as is with the shower wand only. No need to mix cold in, it just heats to desired temp by flame size and water flow rate. So try this. Turn sink or shower on hot only. If it stays hot, OK. Now adjust the contols on the heater to shower temp. If you want a hot shower then open hot only. If you need a cold shower then open cold only. If you want something else like luke warm, you will have to adjust the heater control and use hot only. The heater senses flow rate to start the burner. if you are using hot and cold you probably are not getting consistant flow high enough to keep the flame on. I am pretty sure you need 1.8gpm min. at the heater. Not sure how much RV pump moves but chances are you split that by using cold valve as well. I am not sure, but this may be Padilen and Tommy's issue as well? I hope this makes sense, and you may know this already so it is not the issue, but if I remember correctly plumbing is not your forte. Check that out and get back with me. I'm glad to help you work through this.
