The problem might be with vapor lock.

Vapor lock occurs when the engine heat boils the fuel in the fuel rails.

This then makes it difficult to start the engine.

Carry a bottle of water in the vehicle. The next time the engine is hard to start, open the hood and pour the water over the fuel rails.

If the engine starts, that’s vapor lock.
