I know this is an old post, but I was having a similar issue in 2015, except mine dumps a ton of white smoke when it falls on its face.
It mainly happens to go from a dead stop or slow roll to like half throttle and generally only happens before the truck is up to temp.
Like when I jump in and leave work, but it never happens at highway speeds or after it's been running for 30+ minutes.
My fuel mileage also dropped drastically at the same time this issue started.
I forgot to include mods: deleted with a 2nd Gen swap SX369 GDP tuning on EZ Lynk.
