Vehicle in Need of Urgent Repairs ASAP (UPDATED!!!)

I've struggled with myself on whether or not to do this for a couple of days now, but with how bad this situation is and no means of saving myself from this scenario, I really don't have a choice...

My vehicle is my sole source of income and I literally *cannot* make money if it's in an undriveable state. The engine is shot, with the car shutting itself off after about a half mile to a mile of travel, where it basically becomes a brick until I can get it to turn on after a few minutes and sputter a bit further before it shuts off again.

I've checked the oil levels, and they're fine. I also have a full tank of gas, so it's not an issue of an empty tank, either. I have no clue what the problem could be, but my car is not only completely useless in its current state, but also legitimately dangerous to drive with it constantly shutting down on its own. Since the nature of my work demands that I have a working, operating vehicle to do my job, I'm all kinds of screwed and I simply don't have the funds needed to afford the exorbitant costs of getting my car back into an operable state.

The purpose of this GFM is two-fold:

1. To help me pay the towing fees, diagnostics and inevitable repair/parts/labor costs I'm going to wind up incurring from the mechanic.

2. To help cover my rent/financial obligations for the next little bit until I can get my vehicle repaired and back into a drivable state again so I can get back to work.

I'm deeply sorry for being such a bother and relying on you all to save me from this absolute disaster. If it were within my power to do so, I'd never dare ask for help on this scale, and I'm quite frankly embarrassed that I'm having to swallow my pride and do this.

Literally any bit of help you can offer is another step towards me getting this problem solved and back to work again, and again, I'm very sorry for troubling you with this.

Update: God, I honestly didn't expect this to get as much traction as it did... I'm incredibly appreciative of those who've managed to keep me from being homeless+try and get some of these repairs done.

Unfortunately there's been two hitches on my end:

1. The repairs are going to be a fair bit more expensive than I was expecting. It's not just the "mandatory" repairs to get the thing running, I also have to get this thing tuned up to where it can pass smog testing so I can get my tags renewed. My tags are expired and not only is that going to cost more money that I don't have at the moment, the repairs needed to get the vehicle itself up to snuff for passing smog are also going to be substantial in cost and will set me back even further.

2. As of recently, I was hospitalized with a severe infection that almost killed me and has currently left me more or less entirely incapacitated. I may be back from the hospital, but I'm essentially on bedrest, limited activity and meds for the next *month* as I try to recover from a serious illness. Naturally, this has incurred some medical costs, something I was and am not equipped to handle at such an inopportune time.

3. As stated beforehand, my vehicle is my only source of income. If I can't get the tags registered again and things back up and running, then I'm screwed on being able to work and make money, which means this continuation of the fundraiser is also the only way I can cover rent for the next short while as I get things taken care of...

I'm so, so sorry to impose like this again after you all did so much for me already.

But this has just been a Triple Whammy of some of the worst things happening all at once and I just want to get back to work again happy, healthy and no longer teetering on the razor's edge...

If there's ANYTHING you can do to help, no matter how small, there are no words for the gratitude I'd feel.
