2006 Monterey 32 CR twin volvos 5.7 ..was cruising at about 15 knots Starboard engine quit. It wouldn't restart...I advanced the throttle and it started..when I bring it back to idle it keeps stalling. I changed IAC motor..no change. I was told to check low pressure fuel pump ..I will do that once spring hits and I put the boat back in the water..just looking to see if anyone had similar issues
