94,e350,5.8l, 143k miles..
Check engine light off but I will scan for codes since I am not getting anything fixed.

since last October I have been experiencing this suddenly cutting off in my engine.It is most noticeable while I am at redlights.

i took the rookie approach and replaced sparkplugs, wires,rotor,cap.
coil,ICM,TPS,cleaned the throttle body and replaced IAC.I also cleaned and use dielectric grease on any electrical connection I found .
The only thing I got from all that is a nice,smooth adle speed and acceleration.

My problem is at red light when I have the foot on the break. Van would idle nicely while waiting for green light and then bamm! that suddenly cut off. it has never stalled on me but I am afraid one of these it will.

I was thinking maybe the FPR and I will check to see if there is fuel on vacuum line. Other than that I am lost and dont want to be guessing anymore by replacing parts left and right.

Any suggestion on this issue would be greatly appreciated.
