It may sound silly but check your battery leads. I had my jeep down for 2 months chasing different dead-ends after I sank it, all because I had a faulty lead on my battery cable. Sometimes it gave power, sometimes it didn't.

Probably a bad Throttle Body Sensor, are you experiencing bucking,jerking or sputtering?
And when do you experience the loss of power?

Check the fuel pressure. Check for a clogged exhaust.

Check to see if any fault code in the ECU. Is there any backfired?

What gears are you running and what size tires do you have? I think I know what the problem is.
