1994 NG900, 2.3NA, 5-speed. All of a sudden I am getting a sporadic complete loss of power and revs while trying to accelerate away from a stop. This is happening after driving 20 to 30 minutes in 95 degree weather. There is no sputtering, missing or cutting out, it's just a complete loss of any power from the engine and the revs drop down to idle, even though I've got my foot on the gas. If I let off the gas it will eventually come back.. The engine never dies and I can cruise endlessly once I get going. It only happens when I try to accelerate and then sporadically. At first, it was only when I did 1-2 shift, but today it started in 1st gear trying to start off. I changed the TPS thinking it might have a dead spot, but that made no difference. Plugs, wires, cap, rotor, etc. are all relatively recent. It seems to be heat related, as I take the exact same route coming home from work at midnight when the temp is 70, and have no issues. Anyone had anything similar or have suggestions on where to start. I don't want to just start throwing parts on the car that I don't need. Thanks for the help.
