88 Sunrader won't run after warming up.

[Michel F Smith]

I have an 88 Sunrader with the Toyota 4 banger and runs fine until the motor warms up. Then it starts missing to the point of being undriveable but only when the engine is warm. It sat for a very long time. Does that sound like clogged injectors or is there some little switch somewhere that went bad. I am not getting any kind of fault code from the computer.
