Should have bought a WJ

Is it the 4.0L? If so it's probably the Crankshaft Position Sensor.

If it runs and drives above 25 mph, it's not the fuel filter. It would idle fine and then starve for gas under load; you have the reverse of that.

Crank position sensor, throttle position sensor and Idle air control valves are famous for causing these issues on that setup. Also, it should be throwing a check engine light. Go to any auto parts store and they'll read it for free and you'll have an idea of where to start.

My wj cuts out at speed when it gets hot, it's why I clicked on the thread :(

OP here - took a good hard look at it, and one of my spark plug wires had melted to the engine, so it has been misfiring on cylinder 7 - thanks a lot, this repair will be cheaper than i thought!

My xj has none of these broblems :D
