Ok i have a 98 eclipse rs. I just got it out the shop because they said the ecu died. Well I was driving today and it cut off. I wouldn't start at all. I sat for a while and kept trying then it cranked. So i got it home and it did it again. Same syptoms wouldn't start at first then it cranked. Now i also have recently replaced crankshaft position sensor and camshaft position sensor within the last 2yrs. What could be causing this.

Usually a bad ECU.

That would be rare. I haven't seen a "Brand new" ecu for our cars in a long time. That would be expensive.

My bad i didnt mean brand new, i meant rebuilt ecu

Jiggle test all connections with the engine running and inspect for wires melted against the EGR pipe.

check your battery and terminal connections. check alternator connection.

I did checked that and noticed the battery terminals were lose so i tightened them and it ran for little longer before it shut off again

Im thinking its my radio thats causing it to do this. Yesterday i rode with radio off and the car didnt shut off at all. But i do remember that when the car would shut off i had the radio on so maybe theres something there signaling the anti theft. I will probably just take the whole radio out and ride this weekend to be sure, but we found that if i put the key in the door and unlock and lock it 3 times then the car would crank right up. But that gets tiring so imma just take the radio out completely and see how it goes from there

Well I just talked to him and he told me that the anti theft keeps coming and shutting the car down as i drive. Something is coming on and making the anti theft activate but he doesn't know whats causing it yet.

If the antitheft is a ground interupt then jump it with a switch until you figure it out for sure.
