94 Disco runs hesitates and dies

[unimon]

Hi,
I Have a Disco 1 out in Saipan which had been running great until it stalled
without warning while at road speed. After a while it finally restarted but was
running rough. The shop said that the right bank plugs were considerable
more carboned up than the left. They cleaned all it ran again but I barely managed to get more than 5 miles before it happen again.
The wires have been replaced, compression checks ok. New Coil and the only
warning code which was for a o2 sensor on that side was cleared with a new sensor. Prior to all this happening I had just filled the tank. I suspected bad gas but I brought it at a Shell where I always bought it and the right bank only?
Any Ideas?

Hey there. How many miles has it actually gone since fill up?
Is it full service? I had a dodge raider once that got filled with diesel!
It made it maybe 30 miles before it died -In the middle of nowhere.
