I have a 2007 Contessa Bayshore 42ft C-9. Over the past few months, when warming the engine at idle, the engine occasionally (three times) quit and the Aladdin screen said "ignition shutting off in a few seconds". I waited a few minutes and the engine started as normal and continued to run. Recently, on my way from Prescott, Az. to Montrose, Co., while climbing a moderate grade in cruise control, the dash "air heater" and "check engine" light came on for a second and then went out. I fueled up about fifty miles later and added some "Howe" diesel treatment and drove to Ridgway, Co., over some major mountain grades for 130 miles and the coach ran perfectly until coming into town at idle speed and the engine stopped. I pulled off the road, waited a few minutes and started the engine. It started, but took a few seconds for me to get the RPM's up as the engine seemed to be starving for fuel for a few seconds. I put the coach in gear and we drove another 20 miles to our destination and the engine ran normal. ANY suggestions as to what might be the problem?
