Default sputtering and dying problems

Hey guys. Im somewhat new to this forum.
I have a 88 cherokee that has been having problems running.
Whenever it would be sitting at idle in about 30 seconds it would die randomly.
If i tried to drive it the motor would start cutting out intermitantly and die if i was just cruising.
I have already replaced the fuel pump, fuel filter, new plugs, wires, cap and rotor.
I had someone tell me it could be the fuel pump relay or the TPS.
Just thought i would see what your thoughts would be on this. Im gonna go buy a new fuel pump relay today and maybe a new TPS. If that doesnt work then i dont know what else it could be...

Might be as simple as adjusting the TPS. Cruiser54 has good info on TPS adjustments.

Could be... "I had someone tell me it could be the fuel pump relay or the TPS." probably would not hurt to replace as well.

Its really weird. When it dies it doesnt sputter like its running out of gas. The engine just shuts off. It seems like it might be some kind of electrical problem?
Ignition switch maybe?
