    I'm heading to the center in the morning to deal with a very similar issue. It started with the sweep motor humming after the lane had been running for an hour or so. Lane would run fine one day, then after a bit of bowling the sweep motor would hum and kick out. Caps, potential relay all checked out ok. Sweep runs fine from the table circuits. Plugging everything back in and sweep runs normal. Lane runs fine for a few days then the issue crops up again. Motor plug looks good. Nothing in the wireway. Got called in tonight on the same issue. I swapped the potential relays to see if anything happened with the table. Lane runs fine for an hour and then it does what you are describing. Seemed to me like the spot relay was not firing when it should. It also seemed like it would only do it after a strike (or no tap strike as was the case tonight). Chassis was eliminated as culprit. I'm tearing into it in the morning and will post my findings.
    Failed safety course.Question #1:In case of fire what steps do you take? Apparently 'Friggin long ones!" is the wrong answer.

            Is the scoring showing a strike?
            I've had enough of hope & chains.

              This sounds like...
              "STRIKELOCK!"......."dun-dun-dunnnnnn"
              (machine 'locks up' in a strike cycle)

              Bowler throws a strike. Machine runs a long strike cycle as normal except acts like it is waiting for the nine eventhough the bin is full and the BS works fine. You power the machine off/on then the table does a single detection stroke, table and sweep both return home (because sweep is at 270) machine is now on 2nd ball with empty pindeck, you cycle it and it spots fine.

              If this is what you are experiencing then you may have one or more cam swithces double clicking, I'm thinking TA2 mainly. If the cam switches are sticky, going bad, or have stretched springs this can be the result. Should also check the sweep cam switches/springs, namely SB as it is responsible for starting the table to spot pins at 186 deg., one of them is responsible for causing this I just can't remember which one it is.

                    Interesting issue! Glad you guys solved it. The cams are very mysterious.

                      Toby, this issue seems to be isolated to the SS chassis, I think if it happened on your stepper machine it might show up as something else weird and mysterious.

                        Yeah, who knows what the stepper would do in this situation. I've been tempted to throw one of these machines out of adjustment just to see what would happen, but as it is, I barely have time to repair the actual defects, much less the mess I would probably create by committing what is essentially sabotage. Last year I bought parts from a tech who put in over twenty years with the stepper chassis, and he offered me a typed copy of his service notes. I need to send him another nagging e-mail. : )
