1992 V4 115 precision blend

[Busta]

Hello after some advice I have a 115 Yamaha 2 stroke and the fuel pump was stuffed so I replaced it, now the motor starts no worries compression is good But it will only run a couple mins and the stall as if it has run out of fuel then I pump the bulb hard again and same thing Happens again is it a split in a fuel line some where or could it be something else thanks in advance

Are you running from a Jerry can? Cap vent open?

Haven’t tried the jerry can it’s in floor tank changed filter and the fuel was pretty clean looking the fuel lines all look pretty good maybe the the breather is blocked didn’t think of that thanks

Priming bulbs are another one to check as they can get pin holes and draw air. Worth replacing it for the cost of them.
