Stalling 4cyl:( plzz help

Okay so i have a 1990 2.3 with 75,000miles on it lx ive had a miserable time with the stupid autozone control modules , i finally got a working one that is lasting . Anyway heres my problem it will run perfect when warmed up to operating temp. It makes the poor little car sound garbage in a parking lot or garage. What it does it i will start it then 30 sec or so after it will sputter then stall and i wi repeat the starting and itl probably do it a few more times till it stops spitting and sputtering. It acts like it runs outta gas but then starts right up. Ive changed so much on this car, fuel pump, fuel pump relay, alternator, battery, coil, pick up coil, ignition control module, plugs, wires, distributor and rotor, i have checked the vaccume on the egr and it holds vaccume so the diaphram is good also replaced air bypass valve recently along with coolant temp sensor, air charge sensor and maf sensor, also the fuel pressure is a consistant 30 psi. i also calibrated the tps , and now im stuck i have heard the egr position sensor could be bad but i dont wana play the guessing game with 30$ and then it end up not work, i have heard the egr is all to do with idle so i was leaning towards just spending money and seeing if itl fix it but ive wanted to see what any other person would have thoughts on it.

The ECT should be located on the block on the drivers side on the piston closes to the firewall. It's easier to see it if its in the air. It should have just one wire coming out of it. And the fuel pump check valve is in the tank if I remember right... On the fuel pump.

Check the treadmill the little squirrel runs on for loose nuts. Also check the tensile strength of the rubber bands hooked to it.
