No way..I cleaned the ground connections and replaced the fuel filters and was going to do the fuel pump next. I’ll put the stock ecu back on and see if that solves it. I got my TD Vortex from mx locker, I should have known better. It’s only happened once this season but it happened in the air

I have a 21 350 sxf and I have the exact same problem. Randomly bog and stall like it’s starving of fuel. Did you ever figure out what it is? I’m going to put the stock ecu back on
