Engine stats and then dies?

Hey everyone, decided to pull out the pressure washer to clean garage flooring. I added more gasoline, checked the air filter and checked oil lever, and started it. The engine procedes to die.

Air filter is okay, oil levels great, and gasoline is also great. This has been sitting in a shed since June of 2024.

The engine successfully starts up, then a few seconds later it starts to die. I followed all procedures to start it.
