5.0 swap cutting out randomly while driving

[Fletch!]

I have a 5.0 swapped ranger with a t5 and every time I floor it the engine cuts out and it sounds like a Jake brake. after it has cut out it is hard to restart with a jumpstart or just the key. any ideas? I just replaced the upstream 02 sensors and now I am at a loss.

So far all of those except PO174, I'd expect a blown fuse or broken wire. Any chance one of your O2 wires got against the exhaust and melted? That could cause all of those at once. IDK that it would cause the running bad, unless it's the bank 2 upstream sensor with bad wiring causing it all. IF you don't have broken/melted wires, I'd try replacing that sensor with the old one as a test.

I replaced both sensors with some nice new ntk ones and the problem is still present. I will look for burnt wires and fuses
