My 92' YJ wrangler will loose power while driving down the road like it's not getting any gas. After shifting gears there is like a dead spot then it will pick back up and run fine, also wile sitting still at will idle fine for a minute the act like its about to stall out but it never completely cut off. I've replaced the TPS, Map sensor, and the fuel filter.

Check and test the following below:

Oygen sensor
Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)
Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
Cap and rotor

Note:If it doesn't apply, disregard.
