Your fuel tank breather is blocked. As the fuel is sucked out of the tank a partial vacuum is built up and no more fuel can come out.
Check the breather holes in the filler cap or the breather pipe if it has one.

My 929 2001 HAS BEEN STANDING FOR 4 YEARS. BEEN SERVICED SINCE BUT HAS GOT A STALL ON PULL AWAY BIKE IS STOCK STANDARD DOES NOT IDLE SMOOTH FROM THE START WHEN U GO ABOVE 2000 RPM EVERYTHING RUNS SMOOTH IN...

When u service it, did u do a complete service to clean all possible areas gunk can sits on, such as your petrol tank, fuel lines, jettings, float bowls, change your old air filter? Sounds to me it is still quite dirty and restrictive. Do a complete fuel line cleaning service and try again. Cheers.

97 lumina, 3.1. Starts runs smooth, drive for 30

I just recently have been fighting the same problem with the same make/model/year vehicle. For myself, I would drive off and on through the day and it would run fine. Then suddenly after a start it would run rough and die. I would have to wait 20 to 60 mins before it would start again. I had it checked and fuel pump was only putting out around 19 psi. It should be around 41 psi. Had fuel pump replaced and no more problems. Furthermore, now it runs so much better. It's funny how over time I didn't notice how the performance was slowly degrading. Unfortunaley fuel pumps for this car run around $300.

F-I is fuel injection system telling you to clean air-filter,fuel-filter and clean the fuel injector system. This is a good start.

1997 Mazda dies when warm - runs smooth when cool

possibly a bad module------cracked---or???? In any case you may get expansion as engine compartment warms up----module shuts you down. Sometimes really hard to diagnose and just putting in a new module is "spendy"----especially if it turns out not to solve the problem!
