So I bought the car a week ago probably the sale it had the power steering light on so

I grounded the tcm and it turned off. Car runs beautifully and drives well. All of a sudden it stalled up a small hill wouldn’t restart for a few minutes then it finally lost spark on all cylinders the other day. I included a picture of the codes I have. Any thoughts? Has new knock sensor and crankshaft sensor but the wires at the crankshaft sensor plug look a bit rough ( was replaced by garage before I bought)
