Hi Jason,

We've come across these symptoms before and they usually mean a camshaft or crankshaft sensor is faulty. The issue is that they work fine when cold, but when they warm up the fault creeps in. Bring your car to a garage when warm and get them to put it on a diagnostics machine to confirm.

Hope that helps.
