Answers :

It sounds like the coil is breaking down under load. Try doing a fuel pressure test. If you have an exhaust back pressure tester, would try that first. The CAT maybe clogged. If you don't have a tester, you can drop the Y-pipe and see if it runs better in the drive way. If it does then the cat is bad. If does the same thing, then try a coil. Let us know how it goes.
Your alternator or ac compressor might be getting worn, and not turning as free as it should when engaged. Crankshaft warping also presents this issue somewhat but its an all the time rough run thing. does not sound like a throttle sensor, but a crankshaft positioning sensor if equipped.
