Default Jetta won't start-special warm/hot Eng.

Hi! I am happy to find you guys.
I read a lot on this forum as a guest, but I couldn’t find a solution for my problem.
I bought 1 week ago a 92 Jetta 1.8L, automatic and after 3 days to running perfect, the car start more and more difficult. Sometimes start when is cold, but after running for a while, with de engine warm/hot, won’t start again. Leave it for 1 hour and –probably- start.
I have no more ideas what to do. What I did already: replace the distributor cap and sparkplug wires new sparkplugs, replace coil, knock sensor and TCI-H(transistorized/ignition control unit).Also I checked both electric fuel pumps which are working good.
I want to mention that after the car start(if and when –just random), it is running amazing, idle-ing perfect, but when I turn it off.....won’t start again....maybe after it cool down.
I have one more thing to do, in my opinion, to replace the Computer-Digifant II....Should I do this, or you guys have any other suggestion before my last try?
Thanks a lot, I will appreciate your help.
