One of the sensors, map, tps, etc may be going out. Could be a dirty (carbon) throttle body.

Check for bare wires and loose connections. Spikes in the line could cause it to trip. The pump itself could be the cause. it maybe heating up or drawing more power after working continuously for some hours. That is the reason it works again after a reset.

The problem is usually in one of the heat pads in the seat - the heating filament is probably broken and the culprit pad has to be replaced (big job). However, you should make sure the fuse is OK (check the owners manual for location).
When the brakes were installed, one of the ABS sensors was either not installed properly, the wiring is disconnected or the sensor has failed - take it back to the shop that did the work.
