Check the battery voltage with the engine running at medium rpm. Do 
this about 1-2 minutes after startup and again when it's fully warmed 
up. It should be 14.1 - 14.4 V either time.

Check the fuel pressure. Try to set something up so you or a 
passenger can watch it while you're driving. It should be rock steady 
at around 30 psi any time the engine is running.
