Four Consecutive Integers

Find four consecutive 2-digit integers which, when raised to some single-digit power, are each equal to the sum of their own digits. The power can be different in each case if required.

Example:

35 and 36 begin to meet the requirements because:

35^5 = 52521875, the sum of the digits being 35 (the number we started with); 36^4 = 1679616, sum digits being 36. If 37 and 38 had similar properties, we would have the sequence of four 2-digit integers as required. Sadly, they don't, but such a sequence does exist - your job is to find it!
