    On the toll road 4th gear 3,000 rpm and suddenly it stumbles a little bit. When I exit and drive stop signs and lights then all of a sudden there is not much engine power. "Feels" like clutch and engine are not talking.

    Not enough info here to offer much help but sounds more like engine than clutch. You'll need to post more details if you want help diagnosing the problem.

    Could be slow down lights (no bulbs?) and limp mode. Try resetting battery switch.

    a slipping clutch would be a (healthy) increase in engine RMP without a corresponding increase in actual speed (MPH).

    An overall lack of power could be anything from a lost/clogged FI to a complete loss of one bank of cylinders.

    Bad cat TCU is my first guess.

    Not clutch. You'd feel the slipping if it was old. You hear a racket if one of the pressure plate teeth broke. Something else.

    @Meister, its a 348 not a 355 with F1. Something electronic, yes.

    It does sound like limp mode. When you turn the ignition switch on (not start) do the yellow slowdown light illuminate? If not you should check the bulbs

    Thanks all, got rained out this evening so wasn't able to get it out and pay attention to slowdown lights and temps and all. Will do tomorrow and report in.
