engine failure dodge ram 1500 94 on 1994 Dodge Ram 1500

the engine fails, but the fault is not constant, it comes off fluctuations and recovers and has burst on the engine when it fails, and was changed spark plugs, oxygen sensor, cap distruibuidor cables, high sensor crankshaft, the IAC, fuel pump, and continues to fail, the computer does not throw fault codes. thanks for the help
