So I was driving my 2008 escalade esv with a 12 foot small trailer with barely anything in it in tow haul mode, noticed that when i went to accelerate that i was hesitate off the start a couple times. Then i was at a red light went to give it gas and it died.

I tried starting it again and it would just crank over after about three attempts it seemed like it almost wanted to start but would not. I checked for codes there were none present at this time.

I noticed that the temp was at 3/4 which was weird never did it go past half. By the time I got it back to the garage I decided to try to start it again. It fired right up. At this point i had a code p0230 which is fuel circuit malfunction. I then tested for fuel pressure test was fine ran a 60psi with a 2psi drop when adding acceleration for a split second.

I dont know what to check next.

Any help would be muchly appreciated.
