The car was running fine for about 7 years before it was put away for storage for a few years except as it was being reversed into the garage for its hibernation it cut out. The owner just pushed it the rest of the way into the garage and left it there for a few years. A few months ago we thought we'd bring it out of hibernation, what ever caused it to cut out now seems to be stopping it from starting properly now as 9 times out of 10 it refuses to start (no fuel or spark) then on the 10th attempt (not literally but you know what I mean 
) it fires up and idles perfectly 
but after about 5 to 10 mins just as it's warming it up the revs rise to 1200rpm and down again a couple of times and it cuts out and refuses to start (no spark or fuel ) My guess is the ECU is not getting a signal from a sensor in the engine somewhere and is cutting the spark and fuel ? Does anyone else have any suggestions as we really are stumped ](./images/smilies/eusa_wall.gif "Brick wall"){kind=small}
FYI we tried a different ECU,Coil and ignitor,
and had the distributor tested which was fine,can't see any dodgy earths anywhere, also no error codes are being thrown up, so we really need any suggestions that you guys/girls may have 
First pesrson to solve it gets some pickled onion Monster munch and some UM BONGO
