Could be any one of multiple causes. The unit likely has engine overtemp and low oil pressure cutoff. Could be fuel restriction. If theres an Auto Transfer Switch, it may be switching source to utility and shutting down the engine. AND any one the related components could be erroneously effecting shutdown due a sense failure. Call a service tech.

Projector is overheating. Turn the projector off and let it cool for 30 minutes.
Clean the air filter and check all ventilation holes for blockage.
Hope that helps..........

SOURCE: generator is stalling
Not knowing your model # and how old your generator really is - as related to TOTAL RUN HOURS - I can only give you several possibilities of what the problem might be even though I don't know the make & model and what the rated WATTAGE output is.
I also don't know what LOAD you are putting on the Genset or at what RPM you are running the engine at as to half throttle or full throttle setting?? I take it that it's a Briggs & Stratton 4-stroke single cyl, or is it a Honda 4-stroke single/twin cyl engine?
Since it runs good for 30 mins, and then starts to cut out - I doubt that the OIL is a problem even though you ran straight 30 weight - seeings most small engines run 10-30 weight oil as a rule.
I seriously doubt you did any damage to the engine at all unless it was ran low on oil - in which case it should have a LOW OIL cutoff switch mounted in the lower engine case close to the CHECK OIL port.
If the LOW OIL switch is working properly and adjusted properly then you shouldn't be getting cutout unless this switch is mis-adjusted. (ie: mechanically set too low as then when the oil level is indeed at it's proper level the switch would be already shorting out to ground) (See your operators manual for proper setting)
A way to check for proper operation is to temporarily disconnect the (usually) BLACK wire from the LOW OIL switch when the engine starts to cut out. If the problem goes away completely then the LOW OIL switch is either mis-adjusted or else it is going bad from vibration. (Again see your operators manual for proper adjustment and/or check out procedure)
Electronically this LOW OIL switch should be the only thing that would protect the engine from damage should the oil level fall below recommended level. Other then that it may have an electronic REV LIMITER if it's a bigger and more expensive model, but usually not.
I doubt the Maintenance-free Magnetron® electronic ignition is at fault, but could be weak and going bad. Always a possibility, but I would 1st rule out everything else first. Since the Genset runs for 30 mins and then starts to cut out I would look more for like a fuel vapor lock (partially closed or clogged gas cap vent), a possible dirty fuel filter, possible water moisture in the gas tank or in the carb bowl, possibly dirty carb in general along with it's dirty Float Bowl, Float Pin, Float and Needle Valve, and any Adjustment Screws that go Into the Carb Body. That covers everything from a fuel standpoint.
You do know that all Gensets should be started and run for at least 10 mins every 30 days - right? If you didn't know this - now you do! Every good operators manual should state this.
It just doesn't sound like it's starving for gas unless it's building up a (vacuum) or vapor lock in the gas tank.
Having covered everything from an Electronics/electrical standpoint engine wise - there is only one other thing left Genset wise.
What it really sounds like to me (and I personally HAVE SEEN this happen myself firsthand) is that the generator brushes are nearly shot - as in almost worn out. They may be getting too too hot - as from excessive current draw at point of contact, and thus the generator sensing circuitry itself is doing an electrical CUTOUT!!
An added protective Genset circuit feature in that the generator itself may indeed be linked to the engine as a type of REV LIMITER on the Maintenance-free Magnetron® electronic ignition. Again - your operators or service manual should have a pretty good troubleshooting section in it unless you don't have that anymore or never got one if you bought it used to begin with.
It has to be one of the scenarios listed above.
Please post me a reply as to the found problem there, and the resolve to it by following my recommendations above. Also please rate my troubleshooting fix as well.
Best regards and thanks,

Sounds to me like it could be a few things... pretty interesting that it runs and shuts down...sits for a little while then fires back up. Could be something as simple as a bad ground.. maybe it needs cleaned.. if the ground is making very little contact.. the bike would run bad, and because its direct current it has to flow. The metal in the motor frame etc will hold so much DC current.. but *** soon as it load up the bike would stop sparking. Let it sit for a while, DC trickles into the battery through the slight contact, bike fires back up. OR could be bad venting of your fuel tank, or a partial clog at the pet ****.. the first is pretty easy to check, open your fuel cap and start the bike..if it does the same thing then its not a vent problem. One thing that does happen on the Radian, is the reserve fuel screen inside the tank comes loose, and then everything inside the that has built up over the years either partially clogs the pet ****, or the hose, or both. Take the tank off, pull the pet **** off..if it still has two intact tubes with good screens..you probably don't have any junk in your line..but I would pull the line off and blow through it any way... it could be some type of blockage, when the bike sets the fuel seep through, but when it runs it eventually creates a vaccuum that stops the fuel flow. Those are my two first thoughts... good luck!!

First locate the oil pressure switch and see if you can bypass it,then see if it runs. If not check the fuel filter and fuel pump,make sure solonoid for fuel pump is kicking on.

Check the 94282000 cartridge for debris on the filters. If your boiler requires a certain flow rate to come on, then you must get enough flow through the cartridge to make that happen. Also, if your boiler is producing very hot water, the cartridge will self regulate and reduce the hot flow accordingly. try lowering the output temperature of the boiler to resolve that possibility.
