I bought my tta from a guy who hacked it together and shortly after getting the car I was driving down the road and I heard what I thought was a wrench falling out of the engine compartment and rolling down the road and that kinda made sense since it had a fresh engine in it. Well the 1st time I took it out for a serious beating I thought I blew a head gasket since I filled the highway with smoke turns out the engine torqued up and the oil filter got punctured 2 days later I punctured another that's when I figured out a motor mount bolt fell out. The point here is with no oil pressure the 2nd time the car shut off and wouldn't restart so perhaps you also have no oil pressure get a mechanical gauge and verify it
