Attention: TDR Forum Junkies 
1999 5 speed 3500
193k
had a TST box on for who knows how long.
had complaint of dying on hills, no fuel pressure
put a new vp44 and a FASS pump on
ran good for a few days.
now without the box , runs great when cold, but after 15 min it wants to shut down, when you hit 20 psi boost, itsjust like swithing offf, then the boost drops and it come back to life, only to repeat. also was having starting issuse in the heat.
keep it under 20 psi, and it runs without missing a beat.
I later found out that this is what it has been doing for a long time. /
scanned and got a 1689 and a 1693 code.
still have to check the wires, but what else could it be.
Thanks
Nick
