TJ loses power on highway

[Hopper]

and...3 weeks later. After replacing Crankshaft sensor, Camshaft sensor...

it is the 90 day old DELPHI Fuel Pump Assembly that was bad. I actually took it to a family friend's shop and they were flummoxed about it...it had fuel pressure but was also pumping excess air at the injectors.

Fuel Pump replaced on Tuesday and no issues since.

What did you replace it with?

I replaced it with another Delphi. I think there are 3 brands to choose from, Delphi the best of the 3 junkers from what I’ve read

Just had the Delphi put in last week. Fingers crossed.
