4.0L Engine cutting out around 2,000 RPM

I have an 04 Rubicon with the stock 4.0L and a manual 5 speed trans.
While I am driving and going thru the gears, as I get around 2,000 RPM,
the engine quits pulling and does not resume power untill the RPMs fall well below 2,000. It keeps running but there is no throttle response untill I dip down below the 2,000 RPM line. This happens in 3rd, 4th & 5th gear.
It is as if the engine has had a computer or possible an electrical issue.
This does not happen in 1rst or second gear.
Nor does it do this while revving the engine beyond 2,000 RPM in nuetral.
Have roughly 65,000 miles on the jeep.
Is this an issue any one else has had before?
I am just checking before I pay for an Auto Diagnostics.

Thanx
brian

Could be camshaft or crankshaft position sensor. Mine had similar symptoms - cutting out between 2000 - and 2400 rpms (above and below that it ran fine) - and it turned out to be the camshaft pos sens. I was throwing a code though....

You might try cleaning the plugs at camshaft sensor and crankshaft sensor first! I have had to replace both in past but for different reasons! There not that cheap so before I went out to buy you might need the system scanned rather than play the process of elimination game! That can get $$$$ Good luck and keep us posted! Welcome to the forum!
