I can get the injectors, MAP sensor, temperature sensor and the one under the distributor cap. Still the injectors will just stop spraying fuel into carburetor then after it sits little bit it starts right up. Also it will shut off sometimes just at idle.

Good evening,

Check the fuel pressure. It may be a bad fuel pump causing this.

You can rent a tester at a parts store.
