    1. RBH Automotive Says:

      Sounds like low fuel pressure. It will allow the engine to start but will not provide enough line pressure to keep the fuel from boiling once the engine gets hot. This is called vapor lock. once the injection/fuel cools and returns to a liquid state the engine will start again until it heats up again.

      Means your looking at a fuel pump…..:(
