Maybe someone has the answer to correct a long cranking but did start after maybe 10 seconds?
Temp was mid 70's, with ATV not run for maybe a month but on battery maintainer with full bat charge noted. The atv started, but then died a couple times after repeated attempts. But when run awhile everything was ok. Although when starting now I do hear the fuel pump humming but seems to take a few ,"long" seconds before full prime pressure.
Is this typical of a failing fuel pump?
I've priced a replacement fuel pump on eBay for less than $40 so am tempted to simply replace it for good PM. Just had all covers off so looks really easy to replace.
Any ideas?

Hey everyone,
I’m having an issue with my 2021 Polaris Sportsman 570 – the engine keeps stalling after running for about 10–15 minutes. I’ve checked the air filter, spark plug, and fuel lines, but can’t seem to find the root of the problem. It starts up just fine, but then loses power suddenly.
Has anyone experienced a similar issue with this model/year? Would appreciate any advice or troubleshooting tips you’ve tried that worked. Thanks in advance for your help!
