What did the RAC do to get you going and what did they advise?
When you say "no hazards nothing" do you mean the hazard lights wouldn't work as in a total electrical failure? If so I would look at battery main connections, leads to fuse box etc.

What you are saying sounds like the generator/alternator is not supplying enough power to keep the engine running. If that is the case I am sure any competent garage should be able to test for it, failing that a local auto electrician.
A very basic test to see if the generator is working is at night turn the headlights on facing a wall and start the engine and rev it slightly, you should see the headlights come up brighter.

Hi. I suggest you carefully check the entire earth return cabling going back to the battery. This means undoing bolts , cleaning to bright metal and reassembling.
Treat all contacts with suspicion until proved to be innocent. This includes the lug connecting body/chassis to the earth cable.
