10 HP briggs won't stay running

I have a 10 hp briggs on a genrac 5000 generator /Model#205412/0184e1.
It will start and run for about two minutes then stall. I replaced the spark
plug, changed the oil,cleaned the carb and air cleaner,loosened the fuel cap,
disconnected the low oil sensor,checked the fuel line to the carb no problem.
If you try to start it right away, it tries to start but won,t. If you let it set for
for a few minutes it will start run for about two minutes and stall.I also checked
the spark and it appears very weak.

Time to rebuild and clean the carburetor and change the fuel filter if there is one. Sometimes there inside the tank.

10 hp briggs

I took a oil squirt gun poured out the oil and replaced it with gas.I started the engine let it run until it started to stall.I then squirted a little gas in the throat
of the carb and it still stalled. At this point no matter weather you choke it,
prime it ,or just pull the rope start it won't start untill it set's for a while.

Sounds like the flow of fuel from the tank to the carb is insufficient.

10 hp briggs stalls

I think I haven't done a good job explaining the problem. The engine will start
it runs for a couple of minutes it stops. At this point you can prime the carb
with gas it won't start. you can pull the plug and prime the cylinder it won't
start.I've pulled the carb and checked the the bowl it's full of fuel.Has anyone had a mag or coil react this way.

I think it's possible there is a restriction in the fuel line like Cheese mentioned. Give it a minute and enough fuel flows in to fill the bowl and let the engine run. After a minute or two the engine consumes the fuel in the bowl to the point it no longer runs. It cut's off and by the time you get the wrenches and remove the bowl it has filled again.

I have not seen problem with coils that reliably act like you describe. Often they will quit when the engine is good and hot and the heat has time to soak into the coil and it will not run right again until the engine & coil have cooled but that is on a much longer time scale.

All new problem
I bought a brand new mag and installed it. I spaced it .028 from the flywheel.
Now I have no spark at all. I also installed a new plug. I also tried putting the old mag back on.I disconnected the kill switch from the mag, still no spark.

Try setting the coil to 0.10,0.28 the gap is to wide.Hope this helps.Also make sure the coil is not installed upside down.

Found hte problem

I put the mag at .010 clearance the spark was still weak and inconsistent.
Next I disconnected this small metal box that was connected to the low oil
sensor and to the kill switch.Walla it started and ran perfect.Now here come's
my ? what does that little metal box do.
PS I would like to say thanks to
everyone who responded to this post. You helped me help someone who was
a little down on his luck.
Thanks Roger
