Typically a component like an ignition coil causing problems wouldn't start right back up without having time to cool so I wouldn't put that at the top of the list.

It could be a low oil sensor acting up. I'm sure you have checked the oil level.

What you could do is go to the ignition coil and disconnect the kill wire coming from it and see if it keeps running. That eliminates all the engine controls from the equation, like safety devices, ignition switch, etc. With an ignition module (electronic ignition without the battery) the engine shutdown works by grounding the module/coil.

Let me see if I can come with a parts diagram for that thing.

Do you know what the engine on that is = the model ID? Looking at a parts diagram, with the twin it has engine stop diode and a pair of coils.

OK, it must be a GX 620

engine serial is gcad-1094738 is that the number you are looking for?

No, hold on, the GX 620 model is the one.

You could disconnect the engine stop diode (for the twin coils) and if it kept running, it would isolate the problem somewhat.

This diagram, under ignition - the number seven is the diode. Or you could disconnect the coils(1 & 3) individually before the kill wire gets to the diode.

You also have the oil lubrication switches (low oil level) and /or the low pressure (if pressure fed and oil filter) that would serve to stop the ignition. I have a feeling that may be where you have the problem, but no way to know for sure. I imagine your coils are fine.

Keep in mind if the problem is in the oil pressure/level or has to do with the lubrication and the sensors for that fault are accurate, you would certainly want to to fix the fault before running the engine.

right that will isolate it to being ignition then its a matter of which sensor or switch is grounding to kill it right ?

Yep, and it's really just a good place to start. If the coils or kill diode were at fault, it would be conclusive on what to replace. If it's not in those parts the other direction would hold a number of other possibilities. I don't know what kind of shutoffs (if any) that generator would put on the engine.
