Default 94 12 valve fuel help

ok my dad has a 94 12v. the motor keeps dieing like its running out of fuel, right before it dies we hear a (tic tic tic) sound and he lets off the peddle it will die.. things that i have done is new lines from the tank to the motor,new fuel pump and filter. the truck is all stock. fuel presser is 19 idle 28/30 wot@ 2700 rpms. oh and when we go to prime the pump its still full of fuel.

it does it on load/just driving down to road unloaded. it wont do it at idle. i think idle is set at 700 or so.. we are thinking the injector pump is dieing.

I know you said you have good fuel pressure but can you pin point the tick to a certain area like the lift pump?
