90 gt having a wierd problem!

[no_slo_5.0]

ok guys i dont post on here much so when i do usually very few people take time to read or help but anyways here it goes. i bought a 91 gt 5spd car a few months ago and it has this wierd thing that happens to it when i get on it and shift at like 5500 it just falls on its face. if i let out of it and get back into it its fine. btw its all stock. i havent had time to do much yet but im gonna pull the codes and stuff tomarrow and see what i come up with. if any of you have any ideas please let me know im kinda lost. thanks in advance.

sounds like maybe your fuel could be getting cut. Get a fuel pressure gauge and see what it is doing

Your sig does not list any mods, so I would guess that you still have the stock engine. The stock engine runs out of power above 5100 RPM. Revving it past that will produce a considerable power drop off.

yes the engine is stock. and ive owned a lot of mustangs and never saw one do this b4. im gonna put a fuel pressure gauge on it tomarrow and drive it. after i dump the codes any other suggestions? thanks
