Since you are just fishing... check the ignition coil input/output
coil voltages and the capacitor. Verify spark can jump a large gap
when engine is not running. Check this article:
http://mgaguru.com/mgtech/ignition/ig108.htm
Do you sense that there are "misses"?
I would still check the fuel pressure and the fuel presssure
regulator.

Re: Lost top end power in 88 Cherokee 4.0.
Yes Bill
I agree that it sounds like water in the float bowl, but I thought the
Canadian 88 4.0 was FI. Don't hesitate to tell me I am wrong.
