It cranks and fires up roughly for a second or so and stalls. any clues? fuel pump, MAF, coils? It ran very well on the way to do errands. Got back on car after 5 minute stop and wouldn't fire up as described. on flatbed to dealer

MAF has almost nothing to do with idle - then MAF makes a difference above 4000 RPM.

It would take several bad coils to cause what you describe.

Check the fuel pump flow (at the distribution rail) and fuel filter.

Did you recent get gas or have a lot of rain? - bad gas will do the same.

Fuel reserve light had just turned on. Usually have another 30 miles when it lights up. AAA added 2 gallons just in case but still, engine wouldn't stay on. Dealer just called and they can't reproduce. they said its maybe the fuel relay but unsure. It started right up for them this AM. They are going to drive it more and report. any test they can do to fuel pump?

Came back from dealer yesterday, they couldn't reproduce. Ran fine yesterday. Stranded today. Fired up this morning, went to son's soccer game and then wouldn't fire again. Found TSB on "difficulty fueling" or "running out of fuel" on rennlist. It recommends tie straps on the flexible fuel hoses in the fuel tank. But I called the Indy instead and he thinks its a bad crank sensor. Any ideas. When I first turn the key to the 1st position, I hear the pump priming.

My fathers car is having the same problem. He will be driving to work stop and get gas and then the car will not start waits twenty minutes or so and then the car starts. I have read into the problem some but haven't found too much. I have found that sometimes replacing the one of fuses for the alarm will work on row E terminal 86s, but haven't had a lot of success with that and read that cleaning or replacing one of the ground strap my help, but before I started taking the car apart I wanted to see if anyone had any success.

Sorry, I did not notice that you did not indicate the year and model of father's car.

I don't believe there is an actual independent fuel filter in 996 after 2001 or 2002 models.

Check the condition of your crank position sensor, they are well known for causing a hot engine to refuse to start.

Crank position sensor often causes bad starting sometime cold or at hot start. Very often it is not possible to detect by diagnostic tools. PIWIS etc.
