Port engine problems

Would help to know which engines we are dealing with here. 1998's should be throttle bodied and not carbed. If ethanol gas was used anytime before u acquired her, problems could be abound with the fuel system. But then again electronic issues could be the cause.

Another vote for it being fuel or spark related. If they are separate fuel tanks, it's a good idea about disconnecting the fuel line and sticking it in a five gallon gas can. That would eliminate the issue of a plugged vent. Also a good idea about checking for spark after the problem starts. Still, I'm betting it's fuel-related.

Thanks for the reply's folks. My mechanic finally talked to Crusader and it sounds like it is an oil sending switch that has a habit of shorting out when under load and shuts down the engine. We replaced it last week and the engine runs strong but a lot of rain kept us from testing it on the lake. The dealer we were talking to said he keeps a bunch of these switches on hand as it seems to be a common problem. I am not a mechanic so can't really speak to this, but sounds like a pretty simple fix. we'll see.

Thanks for the input. I will keep you posted.
