my car cuts out... i tohught it was the vss but its not

if i leave the car idling it will idle indefinately
if i go for a drive it will cut out when i brake to a low road speed (hence me thinking it was the vss)
if i unplug the tps the car stalls as it should, if i unplug the maf sod all happens
also if i rev it up then close the throttle while standing still it stalls

i'm thinknig i should try another tps, but not sure thats the fault

My car suffers from rolling stalls

i'll go to stop at a traffic light and just as i dip the clutch it dies, i get funny looks when i'm starting the engine up still rolling

i think the problem on my car is a combination of
fuel pressure regulator
superchip and
air filter
