1980 Nissan 200SX 4 cyl

hi my name is pedro and I got a 1980 nissan 200sx 4 cylinders and the car starts ok and runs ok for the first 5 minuts in the morning or wen the engine is cool. After 5 minuts runing you step on the acelerator and the car start missing like no gas or spark. But the car has good spark all time and the gas pressure is around 35 / 40 psi. I'm thinking in the coolant temp sensor but i'm not shure or if can be something else. Aprecceate your help. Thanks.

2. Inadequate spark/coil, defective spark plug wire.
3. Lack of compression
4. False air leakage.
5. Faulty fuel injectors.
