So I have this issue with my '86 Westy that's got me stumped...yesterday it started missing a
tad, then just it quit on me in the middle of traffic (luckily a block from my house) after
running great all day. It would turn over but just not fire. After tons of cranking I got it
started again, but it was running really rough, no power, very unbalanced, coughs and sputters
when trying to rev it. It seemed to go between running perfectly then terribly every few
seconds. I got it home and it's getting spark, fuel pump is working (pump runs and there's
pressure in lines). Have also have a 1990 Westy, so I swapped out the AFM (no change), coil (no
change), ECU (no change) and the distributor (no change). Funny thing is, this morning, it
started perfectly, but then immediately started running really rough like before. And now it
won't start (no ignition at all) again.

I've had this issue a few times before, but it's always cleared itself up within a minute or
two. Now I guess whatever was failing has done so for good. Anyone have any ideas?

Thanks in advance.
