G22 Runs then bogs, sit for a minute, it will run again

[keith_burns]

On my 2005 yamaha g22 cart I put new 1/4" fuel lines on it and a new pump and filter. It ran great for awhile, but then it started acting funky. It will drive just fine for awhile, then it will bog down and cut out and won't go anywhere. If I sit and wait a few minutes and wait and then push the pedal again it will go just fine and may bog down immediately or it will drive just fine for a bit. Not sure what is going on. I have tried pulling the pulse line off while pushing the gas when it wont go and i get a good pulse but when I hook it back up to the fuel pump I won't see any fuel going through my fuel filter. Maybe a bad/defective fuel pump already?
