MOTOR RUNS FINE UNTIL I GET UP OVER 4500 RPM THEN IT WILL JUST DIE. ALSO THE OIL BUZZER WENT OFF TWICE. DO YOU THINK THE FUEL/OIL PUMP MAY BE GOING OUT?

Sounds like a fuel starvation situation. Be very careful, as you can damage your engine if you encounter a fuel loss a high rpm. Check fuel restrictions, certainly output and the integrity of the pump. Do not run near that 4500 rpm until you rectify this problem
