So the other day I was driving and I hit a small dip on the freeway and ever since my car has started to act weird. So now every time I hit a bump, pothole, dip etc at about 20 mph and higher, I'm guessing my fuel pump cuts out for a half second. Just at impact i get fuel cut off. Now here's the tricky part. First gear light turns green I hit the gas and go the car will start bogging if I give it half throttle or more, second gear, It was also about somewhat. Third gear I would get a buck(small misfire). Also when I left turns it try's to cut off.

2 days later I go warm up the car. Leave my house and it dies. Can't hear the pump, nor any relays click as I turn the key. I had a issue a couple months ago with a lose body to block ground wire that was causing my injectors/fuel pump not to turn on. It feels like the damn near same issue but this time I hear no relays clicking on or off. The ground seems to be fine and in tack but idk I'm just lost at what to do. It's a 86 mustang that I converted to maf.

Sounds like you have a lose connection causing to lose power. Yesterday, my negative battery cable came loose some how and I started to lose power in the highway. Lucky I was driving to school and managed to find the issue and was a quick easy fix.
But I would diagnose a bad fuel pump.

It's definitely something that came lose, I had already changed the pump about 2 months ago.

The inertia switch could be bad, or the fuel pump relay.
