Engine will cut off for a half-second and then back on and run rough and keep doing this till I turn the engine off, this happens most often going up hills after the car has been driven for at least 2 hours and this will happen on a hot day when I am in traffic. Just noticed this also, when I first start the car I hear rumbling from behind me, it is not the antenna as the radio was off, lasts about a minute or 2 and then goes away.
Car does not have any codes and does not happen all the time, I can have it happen and turn off the engine and back on and car can drive the rest of the day up and down hills with no problems or it will keep happening about every 5 or 10 minutes, I was leaning towards a bad MAF or fuel pump, but from what I researched a bad MAF should always throw a code and never heard of a bad fuel pump lasting for 3 months (when problem started), so could the pump get weak when hot?
Should note that a flat highway going 80, I floored it to pass a car and the engine started cutting off and on and when I left off the gas and pressed it just enough to try to keep it at speed, the car started bucking like crazy.
So does the regulator send a signal to the computer when the fuel pressure gets to low, for the FP to send more fuel?
Trying to figure out if I have a fuel or electrical problem.

Just got the car 4 months ago, I have not replaced the filter or done the tranny fluid yet.
