OK, it's happened twice now and I'm baffled. After shutdown, my 2.6/2.3 FI won't restart. Engine starts immediately, but acts like it's starved for fuel. Idles for a while then dies - won't accept throttle. When idling, the Low Fuel idiot light stays on, along with a few others. The first time, I checked fuses and tapped on relays looking for loose connections. No results. Then 10 minutes later - after doing nothing else, it fired right up. Tonight (300+ miles later), it did the same thing again. I checked all fuel and vacuum lines - no results. Then 5 minutes later, just when she's dialing AAA, everything starting working again and it brought us home!

Even though everything's working fine again, I can't trust it not to leave us stranded.

I changed the fuel pump 6 months ago, but it never lit up the idiot lights, so I don't think that's it). My regular mechanic is on vacation until after Christmas and since everything's working again, I hate to leave it with a stranger - especially when it's probably something simple (fuel pump relay?) Any suggestions?
