"I have a 150 that is alarming at the oddest times. Only at idle does it alarm. It detunes itslf so I can't power up. After 2,5,10 minutes because it's ramdom it just shuts off. I can them power up and run all day. At times I can idle for a hour with no problem. I have noticed that when the alarm starts the fule guage has lost power and goes to empty. Then when the alarm stops the gauge starts working again. Any ideas on what is going on here?"
