If the filler cap for the fuel tank isn't tight, that will cause an issue, check the handbook.

Sounds like the fuel pump might be dying also. It has to provide 50 psi all the time.

This problem screams of the pedal potentiometer, i would check that the plug is seated correctly, make sure the wiring is not damaged in any way, if that fails then your only option is Nanocom as advised in earlier post, The only other option i can think of is the MAF sensor as a friend of mine had this problem on a Terrano and after putting in a new pedal we tried the MAF and it solved the problem.
