The problem started a few days ago around town (max speed 50k) - the car started ok, but with no warning, it just slowed to a halt. Wouldn't restart. I was nearly home, so I walked home and went back later and it started fine. The next day, all good for the first 10 minutes, and then the same thing happened at 2 roundabouts and then at a stop sign. 3 stops before it refused to start. Went back later - all good.
Today I took it on a longer run (max speed 110k), and it was surging intermittently, the revs were fluctuating between 0 and 4500. If I put my foot down, it revved up, but took a moment until it actually kicked in.
I have had the car about 9 months, and during that time, most of the wiring has been replaced, as has the fuel pump relay and IAC. Fuel pump relay and IAC just about a month ago.
I apologise for my lack of techinical detail, please ask if for more if you think you can help.

test the resistance of your coil when the car stalls or wont restart after driving.key off!
primary between 1 & 15 terminals of coil s/b .6 to 1 ohm
secondary between 1 and ht (coill wire ctr plug) s/b 7.5 to 9k ohms.

with a 12 v probe test lt. clip to grd and probe the test light to #1 and have someone turn car over as if to start.light should flouctuate on off on off overetc.
If no fluctuation of light ,weak or failed Hall sensor

I should have said the #1 terminal at the coil oops!
