Was it deep sleep or did you get a message indicating you could not use remote start anymore? I was on a trip and remote started a few times. After a few, it won’t let you remote start anymore until you start it with the key or push start.
I had this same issue. Checked the manual, which suggests only sticking the pump in until you hit the first ring on the nozzle. Don't stick it in all the way. It's been working well for me.
