It loses power and i pull over, sit for a little bit then starts like nothing happened, it is brand new.

Try running with a loose gas tank cap.
MAY have overfilled tank wetting the vent element . . no vent air in = restricted outflow.

Tight valves can also cause that problem.

Check the compression.

Does anyone else have any other ideas?

Have you checked for spark when it won't run? That machine likely has a kickstand switch that will stop sparky when the kickstand is extended. I had a GMW that would not start with the kickstand extended. Once or twice I had to cycle the kickstand to get the switch to work. It was not new. Use the kick starter to see if you have compression. If you operate the lever by hand you likely can feel the increased difficulty in rotating the crankshaft on the compression stroke. If the effort is the same all the time, compression may be weak. You might check that you have fuel in the float bowl. There are two methods. Turn the carb upside down, and if there's fuel, it will leak out. Or, there is a drain port that is at the bottom of the float bowl. Most are accessible using a loooonnng flat blade screwdriver. Loosen the screw slowly, CCW, and see if fuel falls out onto the ground. Alternatively, you may have too much fuel in the carb. Do you get any black smoke when it does run? That generally is an indication of too much fuel. I figure the valves were likely set back in Shenzen, and should be ok. The dealer may even have checked them as part of their delivery/assembly. The Wolf brand is not widely spread like the Taotao or Jonway, but I think it is one of the better ones on the market. Parts seem to be a bit better quality. If you have problems getting it to start, first things to check are spark and fuel, especially if it was running immediately previous. If spark, they generally kill like a switch got flipped, and don't muddle around half-working. If fuel, it may slow down, lose power and start to chug and cough, running poorly, but still running until the fuel is exhausted. Figure out which and you'll be halfway to a fix. If you suspect fuel, you can check the vacuum petcock. I think I put a manual petcock on the one I had, but its been a while. tom

All of the above plus this . Look for fuel in Vacuum line going to manifold from fuel pump. Or Cdi box issue is possible ,look at your Cdi boxwith the two plugs facing up if you see any sign of a dimple or bubble or swollen section on box anywhere it probably over heated and ruined it , when it dies can you fire it up immediately ,or must you wait for five or ten minutes ?
I think it's the Valves 80% of the time that is it ... If it's cold and you fire it up warm it up take off and the first time you slow down it shuts off and wont fire right back up and takes 10 minutes to start after that it's the Valves

There are videos in the tech section on how to adjust the valves. The main thing is to have the cam positioned so that both valves are closed and the piston is at TDC on the compression stroke. Valves are usually set in the pre-delivery dealer maintenance but sometimes all that is done is test it to make sure it runs. Checking for compression by rolling the engine over by hand is usually sufficient. Make sure you disconnect the spark plug wire and prop open the throttle. There are compression test gauges available also.
The slowdown and quit sounds more like fuel issues.

Yup. I'd vote for a slightly lean engine condition caused by low fuel flow. As the fuel level drops due to poor flow, the mix slowly gets leaner and leaner, finally being too lean to run. You stop. As you sit, the fuel slowly fills the float bowl again, and off you go. For a while. I would check the fuel flow with vacuum applied to the petcock diaphragm. Pull the fuel line from the carburetor, and direct it into a clean Coke bottle. Yes, it must be a CocaCola bottle. They are clear. Ok, any bottle you like, but it has to be clear. Apply vacuum to the petcock diaphragm. Fuel SHOULD flow, full-fuel-line-diameter, no dribbles, no weak plopplop, full flow, as long as there is fuel in the tank, and vacuum is applied. If not, check the filter, check the outlet from the tank. Check for blockage in the fuel line itself. Until you can get full flow as long as you desire, you will have problems. If you HAVE full flow, I would consider plopping in a replacement CDI. You can get them at low cost, they are easy to install, and you can carry a spare in your pocket to swap in quickly when the thing misbehaves. I doubt valves would act that way, as I doubt the heat would dissipate or increase that much unless you lived in NM or NV or AZ, TX, too. HOT places. If it were valves, you would slowly feel the loss of power as the heat increased, and changing the throttle position would have little effect. I think. tom
