I have a 2002 x-star. Vortec MX LT-R 350. It stalled today while pulling a skier. It took about three turnovers until it started. Tried skiing again and the same thing happened about 200 yards later. Took about four times to get it started. We called it a day emptied all the weight and it drove fine at wakeboard speed all the way back to the dock. When it died there was no stutter or anything. It would just stall. I am on staycation with visitors from out of town and am planning to ski almost every weekday so I would like for things to go smooth. It is hard to diagnose since it runs so nice other than those two incidents. I just got this boat and it is new to me. Thanks for any input.

My boat started sputtering and missing at 1/4 tank full. As the fuel splashes around, the fuel couldn't get picked up constantly. I now keep the fuel level above that and no problems since. This would be one of the easiest fixes if that's all it is:o

How much fuel was in it? When was the filter last replaced? Has the fuel pump ever been replaced?

Are you bumping the laynard? Is it loose?

Ouch. Sounds like another fuel pump has bitten the dust. Not good...sucks that it's been happening to so many folks on vacation.

You're gonna need to either replace the pump, replace the pump module, or have your dealer replace the pump module.

A search will detail the diagnostic procedures, but you need to push down on the little Schrader valve that you'll find somewhere on the fuel rail. Key on, let the fuel pump spin up, push the valve see if you have any pressure in the rail.

Does the LTR have a return fuel line, is the pressure regulator on top of the in-tank fuel pump?

The fuel pump was recently replaced before I got the boat. The tank was full. I do not know about the filter. I read on another thread that I have to get the fuel filter from Mastercraft. I could not find a lot of info on the process of changing the fuel filter.

We found the problem. One of the pins was not making a good connection on the quick connect wire harness to the fuel pump. It looked like maybe someone put a probe to a voltage meter in the female side of plug and it no longer was a good fit for the male pin. Problem solved. Thanks for all the help.

Had same problem with my 99 Maristar. I wonder how many pumps have been replaced due to a bad connection at the pump. Glad to here your up and running again.
