2007 Land cruiser, fuel filter???

[Erez4x4]

Hi guys,
I have a problem,
when we drive off road to high elevation (10- 11,000 ft) the car is loosing power
and then turn off and wont start again until I open the engine hood and disconnect the fuel hose from the fuel filter and then there is a lot of air pressure released...
I re-connect the hose to the filter and the car will start again.
Any idea what to do so its never happen again???
Please see the attached photo (where is the Green plastic to release the hose from the filter)
Thank you all.

This has to do with the charcoal chamber or something like that. To avoid this, do not fill up over 3/4 of a tank when in high elevation when the temp is hot. You can also open that gas tank and release pressure like that.

Could be the crappy "green gas" for the Communist State of California....to much ethanol which does not like to work well in high heat or at high altitudes. Kinda like causing vapor lock?

Not Topping gas tank after gas pump auto shuts off (per owners manual 03-07) along with the above suggestion are good possibilities for sure.

Here one other possibility:

Snowy (see signature) PO complained of same issue, although didn't disconnect anything just waited. Finally years later after being tested multiple time, Toyota Dealer replaced fuel pump. Fuel pump was never reported as bad during testing. Dealer even drove to high altitude with test equipment connected and could not find issue or duplicate. After replacing fuel pump condition (shut down) never repeated again. This was reported more in 06 than in 07's. For some reason Toyota Dealer kept focusing of fuel pump.

Could be seeing this issue:
Engine shutting off during long trips.

Another long shot guess....would be MAP senser not compensating for high altitude. The map senser should recalibrate computer for high altitude so engine does not run to rich [or to lean]. Back in carburator days you had to lean the jets way out or they would flood/run to rich and also advance engine timing about 1 degree for every 1000 feet above sea level. Years ago when I was service manager at Laramie Motors in Wyoming and we made a ton of money off tourists trying to drive through the mountains with vehicles not set up for high altitude. The map sensers solved this on computer controlled non carburated cars. We also used to see a fair number of small air planes come to our small airport from out of area and they would stall out due to flooding for same reason.
