200 Starts fine then stalls
 

Need some technical help. I Have a 200 T its and old car but runs good, it starts fine, runs great when warm, but refuses to idle then stalls after having run for about a minute. Then its hard to start, I live on a long hill so I let the car idle in Neutral til it dies then bump start in 2nd , it fires an goes, this happens for the 3-4 minutes, have to idle it at 1500-2000 RPM to keep it running, then its fine after that and all the rest of the day.

I am a decent mechanic have a CD (Manual) and a DVM, so have tested most of the temp sensors, replaced the O2 sensor, Multi-function sensor, new plugs, wires, cap, rotor, and that wierd PVC hose that seems to suck itself shut. I did check the Fuel Regulator Heater, it shows 0 ohms, book says 25 ohms, but the junk yard didnt have one, any ideas on this Fuel Reg heater?

As I said the car runs great when it first starts then after about a minute idles poorly then dies, once its run for about 5 minutes all is well.

Any inputs would be greatly appreciated. Thanks
