Hey guys, Here's the problem. The truck rides fine for a while, but after a while of driving, the fuel pressure will drop to almost zero. Sometimes it'll stall, and sometimes it'll try to boost the pressure back up. It seems like its only when I'm hitting the throttle. I can get it to stall without hitting the throttle but it has to idle for a long time. It doesn't throw any codes, other than the one time that it threw p1232, which is something about a fuel pump circuit malfunction. When it completely stalls, the battery light, and the CEL light turn on. I've tried a new resistor, switching the inertia relay with the hi/lo relay, and also bypassing the resistor altogether. new resistor did nothing, switching the relays did nothing, but bypassing the resistor altogether got rid of the problem. Here's a video:

What could this possibly be? Should I try replacing the relay? Anything else it could be?
