2013 SWT, 2200 miles, putting along, not working hard, no warnings (none noticed at least), engine dies as though it ran out of gas. Did a restart and it started but ran poorly for about 30 feet, died. Engine siezed. Got it home the next day, stripped it down enough to look in the spark plug holes and exhaust. Nothing obvious yet. RAVEs move a little so they appear to be free. Some very light scoring on the PTO side piston. Tops of the pistons look OK but I have a very cheap scope and cannot get good view or resolution.
My thought now are to pull the engine out of the sled before taking top end off. Manual says if I take off the RAVE Link Bar 'B.U.D.S needs to be used to set the position. My expertise on these motors is limited. I should probably take the motor to someone who knows what they are doing. Just throwing this out there while I continue to diagnose. Any thoughts or ideas would be appreciated. Thanks.
