Mazda B200I truck, pulls and turns off

Hello, I apologize I have a big problem with Ni Mazda B2600i truck, mod. 1991, and I need it, the fault is that it works very well for a while or I start and circulate by a section of 4 to 5 km. And suddenly begins to pull the black smoke and turns off, the curious thing is that I leave it 1 or 2 minutes and work well again by another section, already check the fuel system and okay. It can be. Please, they are urgent to help me, I will appreciate them infinitely.

I have a B4000 Mazda and mine is turned off and already made almost everything and with respect to your fault it can be the iac vavula or the oxygen sensors check it and talk to me.

Hello good day, you have given me a good clue, I thank you, I will carry it out and I will talk to you what happens, you soon have you well

You have to check the conditions of the ignition system (spark plugs, cables, coil and module or pill) the resistances of each component
