Question type: Maintenance & Repair

I'M CONFUSSED, MY SUBURBAN WAS RUNNING GREAT WHEN I WENT INTO THE STORE , I COME OUT TEN MINUTES LATER IT WON'T START UNLESS I TAKE BREATHER OFF AND PRIME IT WITH GAS WHEN I PUT BREATHER BACK TOGETHER IT SHUTS OFF LIKE ITS NOT GETTING ANY AIR IS THERE ANYTHING THAT WILL CAUSE THE ENGINE TO STALL OUT OR NOT START AROUND THE AIR INTAKE AREA THAT I CAN CHANGE BEFORE I DIVE INTO A FUEL PUMP. NOTE THAT THE FUEL FILTER AND THE FUEL PRESSURE REGULATOR HAS BEEN REPLACED THIS YEAR.
