I would be looking for another engine, before it dies completely. Were the heads recoe'd 5 months ago? Machined etc? Or just cleaned and replaced with new gaskets? Sounds like the second option to me. And your temp sensor seems not to be doing its job either. Genuine 3/4 temp is not enough to stall your car. I am agreeing with "wanna". You may have cooked it.

Starting problems could be CAS or ingntion coil. If it has weak or erratic spark then it will be rich A/F.

they were completely overhauled, new top set gasket, new spark plugs, new thermostat, new water pump..

the engine is starting but its struggling to start now.. even more then before though

Just a thought, are you running decent quality coolant in your cooling system? As you probably know, water boils at 100c and the pressure cap takes that up to about 108c. Your cooling system is designed to run as hot as 130c and if the coolant is not up to the correct (50%) mix the system will just boil the water out of the overflow bottle and suck air back in, same as if you had a blown head gasket. There a few good anti freeze/anti boil coolants but for price and longevity, Nulon is one of the best. It takes your boiling point to 132c @ 50% mix with soft or demineralised water. Using straight tap water is not recommended as it reduces the protective qualities of any coolant.

the dudes should have a device that bolts to the radiator cap neck that looks like a big thermomter that will show if it's got a blown HG
