Pipes wont collapse if engine is reved stationary , engine needs to be under load as when accelerating hard up hill onto a highway on ramp . Believe me this is not a wind up it has happened to me on a Vauxhall Frontera and now a Dodge Journey ,for an hours work why not try it just put a short length of drain pipe into the induction pipe at the softest point .

Burnt/slipping clutches will cause a code and likely put it into limp home mode (P0700 & CEL)- not likely that
TPS errors should cause a code (P2122 to P2140) and probably limp home mode - not likely that
Clogged fuel filter or kinked/collapsed fuel line should set code (P1093 or P0087) and CEL
clogged air filter or supply makes sense on paper but seems unlikely to me. check the filter minder. will be in the red long before the vacuum pressure gets high enough to collapse the intake ducting
try unplugging the MAF sensor and see if it behaves the same
