I have a 7k watt Kholer LP generator. When I am parked I can run the gen for as long as I need with no problems. When I run it while driving with ac on, it will shut down after about 10 to 15 minutes. When I shut it down with the switch it shuts down like its starving for fuel, but when driving it shuts down like a switch, no rumble just off instantly. Looking for anyone with a similar problem. Thanks.

Some have a low oil level
cutout switch. When the
oil 'sloshes' and uncovers
the sensor, the generator
shuts down. Check the oil
level.

might try checking oil level, if it is a little low, might go below safety switch, which could stop fast. Mine has stop before only under heavy breaking.

It could be an air flow problem, resulting in overheating.
Can you remove the door and take it for a ride?
Can you put an electric radiator fan on the grille in the door?
Does it keep running if you run a hot wire to the coil?

My 5500 gas started cutting off on bumps, etc. Then started surging when parked. I figured time for a carb rebuild. Went to put a wrench on the carb and the top bolt was backing off. Tightened it back up and all was well.

I doubt that its a problem with the oil level. If it runs for 10 minutes before it starts the problem. I would first look at an overheating problem.

Hi Kenbert.
You didn't mention - is the AC running when parked? Or is it under load when parked vs driving?
Also, what year is the unit? How many hours on the Genny?
I have a similar problem that I think I have figured out and planned to post all about it here when I'm done.
Mine will run for 13 minutes under load (roof AC) and then shutoff. Under light load basically charging phones or running playstation, it will run forever.
Does your vaporizer or shutoff valve ice up just before it dies? The shutoff valve is on the bottom right where the line from the tank connects to the genny. The vaporizer is the pressure regulator looking thing in the top left, it tucks into the shrouds around the engine.
I may be the most expert person on this topic right now! I've spent alot of time diagnosing mine and I am dropping my propane tank tomorrow!

My genny will run with both ac's on while parked. It is a 1995 with 300hrs. Just recently replaced the voltage regulator.

Well not exactly the same problem I have, but one problem unique to propane is that they may run too cool. At least at the vaporizer.
Will it run a long time with no load or with NO roof AC on?
I don't believe these units have much for "sophisticated electronics" as far as the engine functions go.
Could be you have some recently added airflow obstruction - like a mouse nest or mud wasp nest. If it impedes airflow over the evaporator, eventually the LPG stops evaporating and the engine floods and dies.
Also, you mentioned having work done to yours. Were all the shrouds and covers put back on? Even the one that wraps around the cylinder head that you can't see when the outer cover is on? The propane units have extra shrouds to guide airflow around the head and over the vaporizer. If you have a shroud missing or gone you won't have the warm air flowing over the vaporizer.
I would expect that while sitting still the genny runs hotter than going down the road. Check your evaporator for ice or heavy condensation next time it dies. This will indicate an airflow problem.
You may simply have to blow out the fins.
Now, I did just think your problem may be the same as mine here's how. Sloshing! When you drive the Liquid Propane in the bottom of the tank will slosh around. Liquid Propane has oils dissolved in it. These are called "cracking oils" by old-timers. Long story here, but just believe me for now.
They will eventually evaporate off given enough heat and time. My tank has ALOT of this oil in it because the previous owner didn't use the genny much (56 hours)so all they really used were vapor-operated appliances. You may have enough in yours that it will slosh and hit your pickup tube and get sucked in to the pickup line.
This oil evaporates slowly or VERY slowly depending on ambient temperature. In my case, the evaporator fills with oil, kills heat transfer, and eventually the genny dies due to ingesting liquid propane with high concentrations of this oil.
To find out if this is the case, right after your genny dies turn the tank off and look at the evaporator. Is it icy? Then unhook the vapor line from the bottom of the evaporator. This is usually a larger flex line where the liquid line is a small metal line. if oil drips out you have the same problem I have. The oil will eventually evaporate off for the most part. However - a word of warning the residue smells VERY strongly of gasoline and the smell that they put in the propane. It will stay on your hands for nearly a week, and in your clothing and hair for a few days.

And if it's ovefilled the crank aerates the oil and causes it to shutdown as it reads the aerated oil as air so it thinks the oil level is too low.
