1998 Ford F-150 Engine Shakes and Shudders

I have seen at least a dozen blog posts from people with this exact same problem, and I have yet to read a true fix for this issue. I have a 1998 F150 automatic 5.4 liter V8 with 130,000 miles. This problem started about 18 months ago. Sometimes when shifting from first gear into second, the engine shakes and shudders violently. The Check Engine light would come on for a few days and then go out and the truck would run fine for a few weeks and start the process all over again. Sometimes after running for a while I would pull up to a stop light and the engine would act like it wanted to stall but didn’t. I had it checked out by my mechanic and he said it needed a new ignition coil. I had it replaced and that fixed the problem for about a year. Then it started doing it again. Again I had an ignition coil replaced. That fixed the problem for about 3 months. After the third time I had all 8 ignition coils replaced. Well it lasted about 3 days before it started shaking and shuddering again. The Check Engine light comes on sometimes and after a few days it will go out. It’s not the transmission, it’s the engine. Do you have an answer for this? I keep reading on F150 blogs about little fixes that don’t work; Spark plugs, Plug wires, Fuel filter etc.
