Customer: external
JA: What is the model/year of your Toyota?

Hello. My name is ***** ***** I am happy to assist you today. Give me just a moment to review your post, and I'll be right back with the help you need.

I would start next with installing a fuel pressure gauge and monitor the fuel pressure while the problem is occurring.

I would also scan the computer system to see if there are any fault codes setting.

Check these for me and post back and we can work from there.
