I have a 2014 RZR 1000 4 seater. We just replaced the radiator and fan and the bike was running good. Drove it around the block and it ran fine. We loaded it up and drove an hour and half to ride. Unloaded it off the trailer fine. Got ready to go on a ride and barely made it out of the gate and the bike died. Now we can't get it to run. We also recently put 33" bkt tires on it. We just installed a new fuel pump because the fuel pressure was low but that didn't fix it. We had the battery tested and it is good. The bike tries to start or starts for a few seconds and then dies. It sounds like it is out of fuel. Please help!
