What might cause an SR car to shut off while cruising in 5th gear? Lights and dash shut off, loss of throttle response, but I'm rolling around ~50mph so I kick start the car back on after a few seconds and its all good again.. Until cruising at steady throttle shuts it off again.

This happens after about 30 minutes of cruising, seems to only be in 5th gear so far. I let it idle for 30 minutes and it purred away no problem. ECU Masters Black with flex fuel. This issue just started coming home from my first ethanol fill-up after 6 months of normal 91 pump gas. No issue with pulls or transient throttle.

Ignition wiring? Fuel pump wiring? Where do I start?
