Bike randomly died

[BigRiig]

I was riding into work today and the bike randomly died. For context, I ride about 50 miles to work, mostly freeway. I average roughly 70-75mph on the freeway and once I hit the city streets, I am in stop-and-go traffic until I hit my office (roughly 4.5 miles). I've done this ride one a week for the last few months with no issue.

This morning, while coming through the city streets, the bike randomly shut off at low speed. The FI light was on and when I tried to start the bike, it would crank but not start. I shut it down completely, turned it back on, and it started right up. The bike didn't show any signs of rough idle or any other problems. I kept riding and about half a mile later, it shut off again. Same thing, I tried to crank it but it would only crank and not start. Shut it down, turned it back on and, BOOM, fired right up.

Made it the rest of the way (roughly 1 mile) with no issues. My first thought was low oil but I quickly checked when I parked and it was within the two lines in the site glass. Second thought was bad fuel but I filled up when I left my house and no issues the entire drive. Plus it was mixed with the 1/3 tank of fuel already in there.

I also checked for fault codes and found none. I haven't done any major repairs or modifications to the bike in about 3K miles so I don't think I could have left a loose wire or connection. Any thoughts?

UPDATE EDIT: On the ride home the bike sputtered or shut off probably 8-10 times. When it sputtered, it almost gave the feeling of running out of fuel. The outside temp was also much hotter than this morning. The last time it completely stopped running, I had a random thought to push down on the fuel cap and felt a faint 'click'. I rode the rest of the way home (~2 miles) with no issue. I don't know if this could be related to the fuel tank not venting/pressurizing correctly. I have owned the bike for 10 years and have never encountered this issue.
