Anybody else have any idea on why it would be running so great but randomly and intermittently just dying? It starts right back up after and runs good again. Terminals are tight on the battery

You might want to check the male end of the pin connectors where it plugs into the cdi unit ,i had one of the pins one break once .the pin was stuck in the connector so it would still work intermittently .a real head scratcher to trouble shoot .but it would cut out as you are describing on a landing or a jolt .may be worth a look

Same thing happened to me too I am now searching for an OEM cdi igniter I tried one of those chinese Venon aftermarket CDIs on ebay but made the ski very hard to start. I dont blame the CDI but think it didnt like my TBM total loss flywheel any body got an oem cdi ? 2004+ try parts wanted section
