I have a 2006 tiara sovran with a Kohlar 7.1 (7.3?) genny. It starts and runs good, but after an hour, hour and a half, it shuts down. It will start back up, but will not run more than 5 minutes or so. so far I've changed the fuel/water separator, the in line fuel filter, and the impeller. It makes good water, so I dont think it is a heat issue (that is the thermo coupler is not causing the shut down, I think) Any other suggestions? I really dont know.
