Primes and begins to start, but then stalls out. Think it's a fuel supply issue. Good on oil and spark plug. Thoughts?

Here are some common troubleshooting steps to help you identify and potentially resolve the problem:

1. Fuel Supply:
   • Check the LP (propane) fuel supply. Ensure that there is enough propane in the tank.
   • Check for any obstructions or kinks in the fuel line.
2. Air Intake and Exhaust:
   • Make sure the air intake and exhaust are not blocked. Lack of proper ventilation can cause the generator to shut down.
3. Choke Position:
   • Check the position of the choke. If it's set to "Choke" for starting, make sure to gradually move it to the "Run" position once the generator has started.
4. Fault Codes or Indicator Lights:
   • Look for any fault codes or indicator lights on the generator control panel. These can provide clues about specific issues.
5. Oil Level:
   • Check the oil level in the generator. Some generators have a safety feature that shuts them down if the oil level is too low.
6. Spark Plug:
   • Inspect the spark plug for fouling or damage. If needed, clean or replace the spark plug.
7. Fuel System Issues:
   • Inspect the fuel system for any leaks or issues. LP generators may have a fuel filter that needs to be checked and, if necessary, replaced.
8. Carburetor:
   • The carburetor may need cleaning or adjustment. If it's clogged, it can lead to stalling issues.
9. Battery Voltage:
   • Ensure that the generator's battery has sufficient voltage. A weak or dead battery can affect the starting process.
10. Generator Load:
    • If the generator is under a heavy load, it may shut down. Try starting it without any load and then gradually add loads.

Then one of your statements must not be true. the fuel pump usually is ran by a relay off the oil pressure switch, so if engine stalls fuel pump turns off. There is relay as well. Follow wiring from pump to relay,
if it only starts when primed, then fuel pump must not be getting power at all, suggesting relay, or fuse.
the fuel pump should be audible when key is turned on, shortly then it turns off.

check your fuel line it might be clogged up and you are just priming it to run it also would not hurt to clean the carburetor

needs a tune-up, spark plugs, wires , distributor cap & rotor, fuel filter, air filter, might need coil also, put some drygas in fuel tank, check all vacumn lines, change oil & filter. DO ALL THIS , IT NEEDS IT i'M SURE, THEN YOU'LL BE GOOD TO GOOOOOOO!!!!!!!!!!!!!!!

try priming it mite work lol

Anytime and engine dies, or is off, while the ignition key is still in the "run" position then the oil warning light should come on since there isn't any actual oil pressure in an engine that isn't running...so I dont think you have any problems related to that. What you'll need to know to diagnose this problem is if after the engine stalls if it is capable of making spark for the plugs when being cranked over. If it won't produce any spark while cranking then I would suspect the Hall Effect pick-up unit located inside/under the distributor cap as they are somewhat prone to failure and often will quit working when warm but will start working again after they have cooled off a bit. If you have spark when trying to restart the engine then its possible you have a fuel related problem such as a weak or failing fuel pump. Good luck, hope this helps a bit!

CHECK THE SCREEN ON OUTPUT OF THE MUFFLER. ITS CALLED A SPARK ARRESTOR, THESE GET OIL FOULED AND MAKE EM A BEAR TO RUN . CLEAN IT UP AND SHE WILL RON LIKE A CHAMP, THE CARB MIGHT NEED REBUILDING AND A SPARK PLUG IS THE FIRST THING TO REPLACE .. IF'N I WAS ANY HELP VOTE FOR ME ...THANKS.. JAY

The pressure regulator is bad,it is allowing the fuel to pass threw to the cylinders,replace the regulator,and a new set of goos spark plugs.This is the fuel pressure regulator.

This sounds like a fuel issue. Could be bad gas, water in the gas, improper gas/ oil mixture (if 2 cycle), wrong or incorrect level of crankcase oil (4 cycle) or a partially plugged fuel filter.
