fuel pump stops, randomly

[4.0B2]

My b2.. I've been fighting a fuel issue for awhile now. To date it has a new pressure pump, filter, and relay... problem is it still randomly dies.

Today I cranked it and let it idle for about 8 mins then it dies and won't start back up and the pressure pump is no longer getting power... after it sits a bit it'll work perfect.

input... GO!
I'm going crazy here. About to go check all fuses and stuff... It's random is what's getting me confused.

check the inertia switch, its on the passenger side floor/firewall. the connectors get burnt and make intermittent contact.

Intermittent dying and the pressure pump gets no power.

How about the lift pump? Does it still power up.
