I have a swiss sk18000 2000 watt runs fine on a small load but when I increase the load it works for a while then cut off for a bit than it starts working again for a little bit than cuts out and so on

Hello again,

I commented yesterday that I had the same problem and had done some tests in an attempt to identify the cause.

I contacted a local mobile mechanic, and when I described the symptoms, explained the tests that I'd carried out, and told him of my theory that the fuel filter might be partially blocked he said, "Yes, I'm sure you're right. I've had to do 14 Voyagers in the last month with the same problem!" Hopeful that he was right, but still a bit sceptical because the car had a service less than a month ago in which the fuel filter was listed as one of the replaced parts, I called him out. He came, removed the old filter, commented that "The old filter is really dirty and doesn't look to have been replaced for at least 25,000 miles!" inserted a new filter and the car has been running perfectly since. There's a marked improvement in the way the engine's running (not really surprisingly!) and this reinforces my belief that most (but not all) garages are only interested in taking your money and not doing the work.

For anyone interested, the process of replacing the filter was relatively straight forward and I think (if I ever have this problem again) I will replace it myself. On my Voyager (2001 RHD UK spec 2.5l TD) The fuel filter is located in the rear fuel pump, situated just forwards of the rear axle, on the driver's side of the fuel tank. The filter is removed by using a spanner of about an inch. Note, once the new filter is inserted it's important to prime the engine well before starting it otherwise it will need to be bled (which is apparently a tricky job on the Voyager!) To prime the engine and get fuel through before starting it, you must turn the key in the ignition so that you hear the pump working (eventually the pump noise should stop), and repeat this several times (we did it about 10 times) before turning the key further to turn the engine over. This process makes sure that there's a constant stream of fuel through the new filter and up to the front where the engine is!

That's all the mechanic did, and it worked! Even my wife's happy (of course all things are relative!)

Hope this helps,
Richard.

A broken/burned motor winding will do exactly this. If you measure it when cold it will look good. The broken/burned winding will only open from heat expansion.

Ignition system. For failures that cut out like this is a common sign of a ignition system failure

8 seconds and stall,..

Sounds like you're starting fine and there's no apparent problem with the engines electrical impulses in regards to wires, plugs, coil etc,..

Which it sounds like you're running off residual fuel but continuous fuel supply is being disrupted.

I'm all but certain if you pull a SP it'll have unburned fuel on it. Check your fuel pump, filter, pressure regulator and injectors

From those symptoms the pump could be faulty, filter clogged and only feeding seepage, the regulator could be flooding it out ot the injectors aren't opening { clogged }

What do you get when you try to press the accelerator when it's running or have you not tried that?

Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
