Why does my Ltr 450 run fine when you first start it but then dies?

Your LTR 450 may run fine initially but then die due to several possible issues, such as a fuel supply problem, clogged fuel filter, or a failing fuel pump. It could also be related to electrical issues, such as a weak battery or faulty connections that affect the ignition system as the engine warms up. Additionally, a dirty air filter or carburetor can disrupt airflow and fuel mixture, leading to stalling. Checking these components can help identify the root cause of the problem.
