04 Marauder engine starting issues

Good afternoon, I was replacing my blower motor today, decided to test the old one with a direct connection to the battery and it spins like a top, so I guest that's not my no fan issue in the car. I have replaced the a/c heater controller and checked the err code which was 24/25. So I replaced the blower motor and same error code. But that is another issue, now the car won't start. When I go to turn on the ignition, it is dead, nothing.

A step back, I also took off old tape by the batter and re taped exposed ground wires. So I pulled the battery terminal off and cleaned those with a battery pole cleaner and the car started. I let it idle for 5 minutes and it just shut off without warning. Tried to start it, nothing, but this time I have accessories, just nothing when I tried to start it, no clicking, nothing. A few minutes later I am able to start it and it will idle, then off again. I am clueless at this point and ready to sell it off.

Looking for suggestions.

04 Merc Marauder, rebuilt title 65,000 miles, seriously thinking I am way out of my league on repairs....

Thanks Fustrated Owner
 
BCM, Blower Control Module. It's behind the passenger side cam cover in firewall. Turn blower on and give it a good tap with a screwdriver handle. See if it works. They develop a bad solder joint. Buy Motorcraft if you change it. There is a writeup on here in one of the sections. A sticky post in the menu of I think do it yourself forum.
 
IIRC the blower motor has 12v constantly with with key on. The ground signal from the blower module varies the speed. Mine went bad a decade ago. Pretty easy swap.
 
My part came in for the module, hopefully Sunday is a pleasant day to work on it. Took the car for a quick spin and no problems with it shutting off...
