16hp Briggs and stratton v twin engine stalls

I have a 16hp Briggs and Stratton Model 303447 Type 1375E1. This engine is part of a carpet cleaning truckmount which initially was powering a pump and blower. I removed the pump so now only the blower is attached. It will start up and run for 5 to 10 mins and then stall. No sputtering or backfiring. I changed coil, spark, air fileter, oil, gas tank & cap and filter and cleaned carb but did not do full rebuild. After it dies it will start up and run for a minute or less with the choke on. After a few attempts it wont start up until it cools down.

Could be the fuel fine is collapsing when it gets hot shutting off the fuel. Have a good one. Geo

Definitely sounds like a fuel problem. Did you replace the fuel pump?

I am going to try and replace the fuel line today. Either this engine does not have a fuel pump or I cant locate it. I have mounted a small tank with a gravity feed line into the carb.

I see you changed the coil, do you have spark right after it dies? If so its back to the carburetor. I have good luck with Sea Foam. Might try that in the gas.

It sure sounds like the fuel flow is restricted, so check the inlet of the carb where the gas comes through the needle valve. It could have something stuck in there or a rubber needle tip that has swelled from ethanol fuel.
