Hi guys I'm baff'd on my car. Story goes running fine, I go for a little drive as I over take a car it dies. Jus stop running with no signs as to why eg. No bangs smoke or anything jus cuts out.
I pull into a layby leave I t for a bit and arrange recovery, fortunately I had a spare fuel ecu with me swapped it over and it started. Jus as I lift my foot of the clutch it died and won't start since.
I've changed the fuel ecu and got a brand new pink relay.
It has no imobaliser on it
And it didn't sound like it was running strange eg on three.
I don't understand why it jus died its had a full hard core service the only thing still original is fuel pump and ignition coil. Everything else is new.

Help please guys
