Could it be tccm ? 2000 blazer

The lights on the dash suddenly switch off and not long after my truck cuts out and will not start again.
I've taken it to a mechanic and they can not find the problem, they sent my truck on to an auto electrician and they could not find the problem either. This has happened before and both places have been unable to find the problem.
I had a callout mechanic come out as I was stranded and he said that the engine was draining the battery rather than powering it, I informed the mechanic and auto electrician of this but they still were unable to fix it.
The problem has since come up again but this time it is worse, the truck will cut out without any warning.
Any advice would be helpful, thank you

When I was changing the rear axle on my 2000 Chevy Blazer 4x4 I noticed a spider gear slipped out of place the axle bearing and seal went bad so I was changing it first time this has happened how do I take care of this do they have to go back in a specific order or can I just line them back up with a pen and they will be ok

Think fuel pump and maybe fyel sensor?

Won't start again. I've put new crank sensor on new plugs, new wires, new distributor, its getting fire, air, gas what can this be

I was driving home from work when truck stalled. Now wont start. I ran it outta gas a cpl times the week before so thought naybe fuel filter was clogged. Changed that still nothing. Fuel pump kicks on but sounds a little whiney. It starts if i spray either into it for a second then dies back out so i know its getting spark. It is also getting fuel to the fuel rail relief valve so i know the fuel pump is working. Anyone know what this could be and what i should try next? Please help

Always does this. After I go somewhere and stop car, the same process will repeat. Is this a anti theft problem and if so, how do I fix, bypass, or whatever? Key doesn't have a chip.

My power locks and mirrors are not working and I can't open my hatchback please help..

It started out splattering. When pressing fuel pedal. And when it was up hill or the gas got low.. the same thing would happen or it would try to shut off. Like it wasn't getting gas. Just to crank it I would have to prime it a few times and feed gas constantly to the throttle. Next thing u know I'm driving home and the fuel line underneath my driver side popped loose and oil was coming out. As black as ever. After cranking it and it running for a few minutes I had no problem cranking it throughout the day. But if there were prolonged periods like over night I would have to feed it gas again while someone pressed the gas pedal. Or if it got hot throughout the summer it would seem to be missing and jumping. It also drank lots of gas. More than usual.
