87 ranger loses power when warm.

I have an 87 ford ranger with the 2.3L efi manual. It will start right up when it's cold and run pretty normal, small loss of power but not bad. Once it warms up there is a total loss of power, won't keep itself rolling in any gear. And have to rev it to at least 3k rpms to get it to move in first. With LOTS of clutch work. Replaced the cap rotor and spark plugs. Replaced the fuel filter about a month ago. Also stopped going into high idle when cold. It is fuel injected but there is no check engine light. Didn't come with a check engine light from the factory and there are no other lights coming on it the dash. Someone please help. I have a feeling it's a sensor somewhere but I don't know where to even start looking.
