[Rovernet] P5 problem persists

[Scruggs Family]

Ah... zebras have hooves too.  I'm sure you typed 'camels' and your autocorrect changed it to zebras... mine does that, too.

Peter: As I mentioned earlier, you first need to narrow this down. All 
problems like this come down to fuel, air, or fire (spark), and air 
seems unlikely.

Checking for spark when it dies is the quickest and easiest thing to 
start with. Then, if you have no spark, start working through the 
ignition system. If you DO have spark, then start working your way 
through the fueling system.

PS: Vapor lock while running (as opposed to after being parked for a 
while) seems highly unlikely. If you hear hooves, look for horses, not 
zebras.

PPS: More likely would be a sticking needle valve in the fuel bowl (or 
Grose Jet if so equipped).
