I had this happen a couple of years ago on my old beast. It was the ignition switch. I turned on my turn signal and the engine died. I went to start it back up while running and KABOOM. I barely touched the key and the engine fired back up with all of the unburned gas in the exhaust system. I kind of knew it was going bad because it ran warm.
gas verses diesel etc two entirely different situations and a bad Ignition switch will have "NO" effect on temperature
I thought it was about the engine shutting down when the turn signal was used? Just a thought.

Ok, this is a answer to the post about my Dutchstar doing a complete electrical shutdown when certain electrical loads were applied.
After replacing the recommend that was posted with no luck. So, while in Iowa, I stopped by the main plant of HWH and was asking questions about the shutdown when lowering the jacks. After a few questions, it was suggested that I might want to check the main 120 breakers on the right rear rails in front of the tires, as Newmar had changed reduced the size from 100+v to 80v in the late 90's. Well, he was right, after changing the one breaker that I had not replaced, the unit runs great and no further shutdowns.
If I read this right when the op turns on the turn signal he loses all electrical power including electrical power to run the engine. I know that it is different but I have a Kawasaki Mule that would just die for the fun of it. I haven't figured it all out yet but when this would happen nothing would work. I checked the fuses, they were good. Checked power to the ignition switch, this was good. Looked around couldn't find any obvious problem started back up and worked correctly. Well they problem happened again. I wiggled some wires and it went back to running good. Happened again , I happened to wiggle only the ground lines going to the battery, worked. So now I know when this happened I can remedy the problem by wiggling the ground wires. Need to do a real fix when I get the chance. All of this is to ask, could a bad ground cause this guys problem and the bad ground be in the turn signal wiring? Also he doesn't say what it takes to restart his rv so don't know I just think that it is either a direct short or bad ground,
