Random power loss??

Electronics are not my thing. I like my simple as a hammer mechanical diesels. Anyhow, sometimes when I start my jeep (randomly, hot, cold, dry, rainy... no consistent trigger) it has no power, won't rev out under load or downshift and feels like it's stuck in second or third gear. If I put it in neutral and cycle the key off/on quick it immediately comes back to life and has full power as if nothing was wrong. So is there a sensor or something that causes this?

Re: Random power loss??

Which jeep/year/engine?
Seems that the transmission is in limp mode. Put a scanner on it to check for fault codes.

Sorry, it's a 1997 jeep grand Cherokee 4.0. No CEL on, but I'll see if I can get it scanned.
