7.3 hiccups

So my 7.3 has really never had any issues but a few weeks ago it left me sitting with a no start situation and had to have it towed... Before the tow came I replaced the CPS cause I keep a spare in the truck and I wasn't seeing any RPM when cranking but it didn't fix anything... So I get the truck towed home and it just sits a few days... I walk out one day just for ****s and giggles to ur and start it and it starts but only after some excessive cranking.... So i take the truck down the road... It's idling fine no issues but the min I pull out on the road it starts burping and farting and herking and jerking... The injectors are clacking and banging and the truck is bucking like a wild horse... So I run around and come back home... No CEL no codes nothing.... It also seems like this is happening more under partial throttle vs full throttle I took a couple videos I'll try to load them here in a little bit

What is your fuel level reading, maybe a Hutch mod is required? Sounds like a fuel delivery/supply problem to me. Have you checked the fuel filter or pressure from the pump?

Cosign on Sous' thinking. Sounds like text book symptoms that your foot may have fallen off of the pick-up in the fuel tank, and or the screens are clogged.
