Twice now this happened: Engine starts fine, runs for a long time just fine. then, I stop for a while for my kids to swim, and leave the engine off for 30 minutes or an hour. I start going again, very slowly, then after a few minutes the engine gurgles, stops. Won't start. I raise and lower the engine to check it out, but can't find anything wrong. After less than 5 minutes I try it again and it starts and runs just fine. Any clue what this might be? This is a 2008 Verado 225 hp.
