Generator runs for a few seconds then shuts down

Hope it's okay to use this Forum for this question.

I'm on the road now.

Typing this from a coffee shop.

Just turned on the generator...I have a 2014.5 AI

3-5 seconds in it stops

the red light blinks on the indoor starter switch

and blinks a number. I think it was 8115

Not an emergency. I can figure this out later but

if anyone knows, that would be great.

Thanks.

Ben

P.S.- It shows that the tank is 3/4 filled with propane.
