Also a classic symptom of the crank sensor being knackered so I'd suggest getting a new one of those 1st

And open up the ECU and check for scorch marks...going forward also pop the spark plugs and see if it is obvious due to the smell of petrol that it's getting fuel, and put the spark plug near an exposed part of the engine or body and check for spark.
