ive seen fuel pumps fail like this they will start the car and run it for a few then as it warms up i fails. when it fails see if you can start the car on carb cleaner. if you can then you are not getting fuel. doesnt mean it is nessicarily your pump it could also be your regulator. well its at the shop now. tell us what they find. if it is your pump it is a pretty quick and easy job. last one i did took me 30 mins

i like the idea of a vacuum leak causing poor milage. very possible. you can take carb cleaner and spray you engine(not in it) while it is running. if the engine speeds up then you are close to the vacuum leak. dragging brakes or binding drive train could also do it. can you put it in nuetral and push it? let us know i know i get 27-28 at 65mph and 23-24 at 75mph. i contibute that to the forester's complete lack of areodynamics lol. let us know what you find

vato zone will scan it for ya. you may have to talk them thru pulling live data...google your local baro pressure...as long as your car doesnt have a MAP sensor the reading is taken from the MAF...make sure you tell us what you find

just an idea but check your battery cables. my wife's 92 pathfinder would stall around right hand coners only till i figured that the un tied down battery would move and the ecu would lose power...start simple

you need a scanner to test your MAF. first check with KOEO and look at the barrometric pressure and compare to the local pressure, i use the third dial on the "decoration" weather staion that i keep i my paint booth for temp and humidity. i dont know how high bend is but here in the front range i expect about 24.5"Hg. next check at idle you will have to look for a spec but id expect to see 5g/sec. and as for cleaning you MAF alittle isopropal alcohol on a q-tip has always served me well. good luck tell us wha you find

just done tires, oil, plugs,wires,valve cover gaskets both rear wheel bearings and a timing belt. need to do fornt bearings next weekend. i also cut out my windshield and glued a new one in last week. i guess thats not bad for 230k. oh yeah in the spring i gotta do head gaskets but i kinda want to re ring the engine at the same time
