I have a 2005 Chevy Duramax it keeps dieing. I have to prime it for it to start up again.It is getting to where if it sits for about a half hour it loses prime. I had this problem about a year ago, then it stopped I'm noticing it gets worse when it's hot or when i pulling my fifth wheel. It's died on me all day today i'ts 103 degress here and not pulling anything. What you think is the problem?
