Sudden Cutout

If the 1300 is like the 993, then look at the fit of the oil filler cap into the rocker box cover.
I had a similar cutting out problem but I put a rubber seal onto the cap and the cutting out went away.
On the 993 the pressure in the rocker box cover contributes to a fuel manifold pressure feed to the ECU.
I used a rubber band to test the theory before delving into more perminant arrangement
