i had a similar issue. When you say power, you mean absolutely no lights or power are coming on at all? or does it come on but wont crank? If power isn't consistent check the terminals of battery and do battery test.

If the power is coming on but it wont turn over some times you have have an issue with VVEL sensor or Module. The check engine light may not be on because the ecu is being drained of the power if it is the first issue I mentioned about battery, however, you can pull up the codes (pending & history) to see if there were any codes.. Do not clear until you fix the issue.
